Spitfire v Hurricane


The question of which is the better aircraft is one that has been bandied about ever since the two were designed in the late 1930s.  Before the reader consigns this blog to the unread pile thinking 'More of the same' I will dispense with any further preamble and state that, rather than immediately state a preference, I think the wrong question is being asked.  Wrong in the sense that one side of the discussion seem to be answering one question, whilst the opposing side are providing answers to what seems to be a different question.  Therefore before I go any further I'd like to clarify both questions and attempt to answer them.

At this juncture I would also like to advise the reader that I am 41, a fulltime wheelchair user, and have never piloted an aircraft in my life.  I am not a professional historian, thus the source material I base the following statements and conclusions on are the works of those who are professional historians, such as Leo McKinstry, Len Deighton, Patrick Bishop as well as those who actually flew the aircraft; Peter Townsend, Pierre Clostermann, Paul Richey et al.  I will not be smothering the following in references for one simple reason; If the reader has got this far (to a degree if they have been interested enough to click on the link to this blog) I am assuming they have a similar knowledge base to myself - if not greater.  They will therefore be familiar with all the literature on the subject, and indeed may have authored some themselves.  I do however have a lifelong interest in aviation, and history, the two marrying quite successfully in my resulting interest in aviation history and therefore the RAF operations in WWII.  My profession is in IT and I hope to bring the logic and analysis I have gleaned from that field to the discussion.

Now to specifics:  The first question 'Which is the better aircraft?' would seem to be simple to answer, assuming we judge 'better' in terms of aesthetics, performance, easy of handling etc.  In those terms we can quite simply compare the Spitfire and Hurricane's performance and say the former is 30 mph faster than the latter, it has cleaner lines and pilots who flew it say it was a dream to fly.  Detractors will point to issues such as the difficulty in taxying due to the long nose necessitating 'fishtailing' the aircraft on the ground as the immediate view ahead was obscured.  However this is not a flying issue, and we are talking about an aircraft.  Thus we could from this conclude that the Spitfire is the better aircraft.  Incidentally throughout this blog I will be using the present tense as flying examples of both aircraft still exist, past tense obviously when referring to wartime events.

In many discussions I have read it seems to me that Spitfire pilots are answering this question.

We now come to the second question, the one which I believe the Hurricane pilots are answering, and to answer this I will be going into the issues in much greater depth.  This question is 'Which was the better warplane?'

I would first like to look at the designers of each in brief.  At the outset I will state categorically that both R J Mitchell and Sidney Camm were among the best of their generation, and alongside the likes of Roy Chadwick, Barnes Wallis et al formed the bedrock of British engineering which helped see us to victory in the war.  Therefore no slight of any kind is intended towards either in the following, and if any is inferred by the reader it is accidental and I offer now my apologies.

Let us start by looking at the problem they were set.  Specification F.7/36 produced by the Air Ministry.  Without any actual knowledge I am going to suggest what seems logical given the subject, that this was Fighter specification no. 7 produced in 1936.  A minor point it may seem but one which may become relevant as you will see.  The outline of the brief was to produce a monoplane single seat aircraft 'capable of carrying eight machineguns and a top speed in excess of 300mph'.

R J Mitchell's pedigree was in high performance aircraft - most notably the Supermarine seaplanes which won the Schneider Cup trophy three times in a row for Great Britain thus allowing us to keep the trophy.  Upon release of the above specification he set to work and ultimately produced the Spitfire.  I mention his pedigree in design as it is germane to the discussion, and I think it is logical that he may have brought all his experience to bear producing a high performance aircraft which could carry guns.  Therefore the design emphasis was on performance.

Sidney Camm's design heritage stretched back to WWI in having a hand in designing some of Britain's first fighter aircraft which served in the RFC.  In the inter-war years he continued in this vein.  Thus when specification F.7/36 was released he set upon it bringing all his experience to bear.  However in his case in contrast to R J Mitchell, I think it is likely he prioritised in a different manner, seeing it as a question of 'How do I fly eight machineguns at 300+ mph on a single seater aircraft to the target?'

Thus by having two entirely different ethos' as their basis both designers came up with solutions which, while superficially similar, were in concept markedly different.  I think this is encapsulated in the view of one pilot who said 'The Spitfire was a racing car, the Hurricane was a tank, and I know which I'd prefer to go to war in'.  The pilot in question was, as you may have guessed, a Hurricane pilot.  However I think the point is made quite succinctly.

In terms of 'fitness for purpose' there can be no disagreement that both aircraft performed their function superlatively well, no better illustration can be seen of this than the Battle of Britain in 1940.  Some may argue that the Hurricane shot down more German aircraft, however I think I am right in saying that if you factor in the numbers of each type in service at the time, the number of victories was proportionally almost identical (I think about 60% of fighters were Hurricanes, and that's about the same proportion of victories attributed to them).

Another factor is in the more mundane, yet vital, area of maintenance.  The Spitfire was (and is) a more advanced and complicated aircraft to build, thus expending more of the scarce resources available to wartime Britain.  This however gave it the edge in performance versus the Hurricane.  However once constructed it is self-evident they would need maintenance, not least of which would involve refuelling and re-arming between sorties.  In this I submit that the Hurricane had the edge not least in two basic areas; to rearm the guns of a Spitfire involved four panels on each wing, these being on the top and bottom taking valuable time.  The Hurricane by contrast only required one panel per wing to be opened, on the underside of the wing.  As it transpired in the heady days of 1940 this would come to be a vital issue.  At some point of course aircraft would need to be transported to an external base for repair, this of course being carried out by road.  With the Spitfire this necessitated transporting the wings and fuselage on lorries to the repair establishment.  In the case of the Hurricane it was a different matter entirely.  The Spitfire's undercarriage was mounted on the wings, a consequence of which was that removal of the wings meant the fuselage had to be transported as a static weight.  By contrast the Hurricane's undercarriage was mounted on the fuselage and therefore the wings could be removed and placed on a lorry, and then the fuselage with undercarriage deployed could simply be towed behind it, a much simpler and faster process.

A brief segue is, I think due at this point.  The Russians requested assistance from Britain in the form of Spitfires, yet what the British supplied was a squadron of Hurricanes.  Initially disappointed by this, when Spitfires later became available to be supplied to them, the Russians apparently responded that they would actually like more Hurricanes.  The thought occurs that this may be due to the simplicity of the Hurricane mirroring the Russian design philosophy which dictated - and to an extent still does - function over form.  They prized capacity to fulfil the function higher than aesthetics.  Also it is likely that the more rugged Hurricane fared better in the harsh Russian climate than the Spitfire would have.  That would seem to bear out the maintenance issue.  Added to that the preference of Hurricanes in the, albeit brief, Norwegian campaign with their greater rough airfield capability and the Hawker aircraft seems to edge ahead on ruggedness.

Survivability is a key component of a fighter aircraft.  The WWII ace Peter Townsend has said 'The Hurricane was composed almost entirely of non-essential components.. I know because I've had all of them shot off'.  This suggests that the Hurricane, due to its' simpler and more rugged construction, was better able to soak up battle damage than the Spitfire.

I mentioned earlier that the Spitfire clearly wins on performance, however in the context of combat flying that is not entirely true.  In the era of propeller driven aircraft, combat between aircraft was not the modern concept of 'Fire and Forget' missiles, but the much harder to master machine-guns.  In this the aircraft had to be pointed at the target whilst firing the guns and crucially stay on target for the duration of the burst.  Obviously when I say 'on target' I mean 'in a position where the burst of fire will hit the target' which in terms of deflection meant shooting slightly ahead of the target.  One failing of the Spitfire in this was the positioning of the machine guns on the wings.  On the Hurricane wing they were evenly spaced in a lock of four on each wing; however on the Spitfire they were unevenly spaced, and this combined with the thinner wing gave rise to a wider spread of bullets, itself coining the phrase 'a spray of bullets' or 'spraying the target.

A core requirement of the tactic of keeping the firing point on target was the ability to turn as tight as possible, either to escape an aircraft behind you or to get into the right position to shoot an aircraft turning ahead of you.  It is a known fact that the Hurricane was capable of turning tighter than either the Spitfire or its' main adversary in the initial stages of the war, the Messerschmitt bf109.  Thus in this respect it was more suited to the requirements of the combat flying of the day.  The argument that the Spitfire is 30mph faster in a straight line than the Hurricane becomes a moot point.

There has also been much made of longevity of each type.  By the end of the war the Hurricane had been superseded by the Tempest and the Typhoon, whereas the Spitfire continued on in service into the early 1950s.  Proponents of the Spitfire point to this as proof of its' being superior.  However, there is a counter to this argument.

As we know, regrettably R J Mitchell died before his creation even entered service with the RAF, much less before it saw active service in the war.  In some ways I think it does him a disservice to suggest that in the next almost two decades that he would not have produced better more advanced designs, building on the success of the Spitfire.  Rather than simply produce a stream of modifications to an already extant design, it is my belief that an innovator of the calibre and quality of R J Mitchell would have looked at what other countries - most notably Germany of course - were doing and come up with better ideas of his own.  In his absence however it would appear that nobody designed a complete new airframe being content to continually upgrade the existing design.  A contemporary example of this is Apple; since the death of the driving force behind Apple's innovation, Steve Jobs, they seem to have been content to tinker with existing designs rather than create anything completely new.

At Hawker, Sidney Camm does not seem to have taken the same approach and his course of action is one which I think R J Mitchell would also have taken had he lived to see it through.  While the Spitfire started life as a fighter and - with a minor segue into aerial photographic reconnaissance - ended its' life as a fighter, the Hurricane saw its' path take varying guises; fighter, fighter-bomber, tank-buster, a ground attack role with rockets, and even in use protecting merchant shipping convoys as a catapult launched fighter.  I have excluded 'carrier borne fighter' from both as I am not aware of any instances where either type were specifically borne aboard aircraft carriers for the specific purpose of defending the fleet (The Seafire although derivative being a different aircraft to the Spitfire).  Thus it proved not only more than adequate in its' original role. but uniquely adaptable and versatile for other uses.  However Camm saw what was happening in military aviation and could see when the Hurricane had reached the end of its' life-cycle, at which point he replaced it with the Typhoon and Tempest to keep pace with the enemy's progress.  In Leo McKinstry's excellent 'Hurricane' he points out that Sidney Camm had a hand in the Hawker-Siddley Harrier, and I have little doubt that R J Mitchell would have similarly been at the forefront of aviation innovation for decades to come.

Finally, I do not want this blog to read as though I prefer one aircraft over the other, but as an even-handed appraisal of the two.  In summary I do think the Spitfire is a better aircraft, but for combat purposes - after all was the whole purpose of specification F.7/36 was to design a fighter aircraft - I think the Hurricane edges it.

Lastly this is not related to performance or indeed how good each aircraft type is in a particular context.  It is related to the justification for the Air Ministry initially ordering twice as many Hurricanes as Spitfires.  Britain being an island relied on imports for some materials, while for others supply was very much finite, as was labour.  The Hurricane took 5000 hours to construct, the Spitfire 13000, and in Germany the Messerschmitt bf109 a mere 4000.  Given that in practice the Spitfire and Hurricane were approximately equal in number of aircraft they shot down in their first real test - The Battle of Britain - I do wonder at the thought processes which accepted an aircraft - the Spitfire - which took almost three times as long to build, with a consequential increase in cost and delay in production.  This at a time when both money and resources were at a premium.  Surely cost and simplicity shoud have been part of the brief?  Curious.

Call Me Len..

Pronunciation.  Some people can't even agree how to pronounce it.  Oh the irony!  :)

However, for those of us who live in countries that at least in part do not speak English, pronunciation can be a total nightmare.  Not that we are perfect either of course - I have worked 14 years in jobs where telephone communication was a core element, and yet I am quite capable of dropping the ball myself.  A case in point; working in a callcentre and asked the caller for his postcode which he dutifully gave.  Up pops his record and using the company convention I attempted to greet him as Mr....  Unfortunately the gentleman was of Polish descent and I paused slightly before attempting it.  You could almost hear the long-suffering, but good-natured, tone in his voice when he interrupted my brief thoughts with 'Call me Len' in a kindly voice.  The call proceeded very well with our mutual understanding.

However, it's not a new problem by any stretch of the imagination.  In 1978 there was an animated version of The Lord Of The Rings.  With the wealth of detail provided by Tolkien including language guides for his mythical races you'd have thought it impossible to drop the ball.  Not so.  From calling Saruman 'Aruman' - unforgivable to drop an entire letter! - to referring to Sauron as Soreon (sic) when the correct pronunciation as per the Peter Jackson movies being faithful to Tolkien is Sowron (sic).  Not that Jackson was perfect - Galadriel's pronunciation of Earandil was a country mile off.  But these could be excused by saying they are fictional anyway and not offending real people.

For many years I have had an avid interest in various eras in history, and have been broadly aware of the reputation of the Borgias, and the main family members.  Throughout this time I have always heard Cesare and Lucrezia pronounced as Sayzar and Loocreesha.  It came therefore as some surprise to hear them in the recent television epic The Borgias referred to with the correct Spanish pronunciations of Chezaree and Loocretzeeuh.  On reflection being a motorsports fan I should have realised at least one of them was wrong - the name Andrea de Cesaris is well-known to me as 'de Chezaris' (sic) so I ought to have known better.

In sport the problem is quite pronounced.  Take the sport of tennis which is televised often, and frequently uses commentators from more than one country - the UK, America and Australia for example.  Then give these disparate countries the same name to pronounce.

Novak Djokavic.

For the viewer - well me personally and I know I am not alone - it can be quite jarring to hear two commentators on the same match refer to the same player as Jokeavitch and Jockavitch.  Is it really so hard for someone to ask the player himself 'How do you pronounce your name properly?' and then tell the rest?  His is by no means the only example.

Tennis is not alone.  Rugby is another case in point - the stadium Parc Y Scarlets is not called Parky Scarlets.  It is Welsh and correctly pronounced Park Uh Scarlets.  Welsh as an entirely phonetic language should be easy - if those concerned can be bothered to learn the pronunciation, and I'm sure the Irish and other nations feel the same.  On which note - Connaught.  I've heard three different pronunciations, sometimes in the same conversation!  Connort, ConnaCHt and Connakt.  Someone please tell them which one is right!

Newsreaders are another culprit.  I well remember listening to election news coverage on Channel Four in the UK.  The National Party of Wales is called Plaid Cymru.  Now remembering what I said about Welsh being entirely phonetic, it is not ever pronounced 'Played Kimroo'!  It is Pl-eye-d Kumree (sic).  That one actually got an email of complaint.

To those concerned with public presentations of any kind; TV presenters, Newsreaders, Actors, Sports Commentators et al, a plea.  Do your homework on pronunciation.  It is not only jarring to the ear, it can be quite insulting when you seem to be at pains to pronounce some things correctly and then give the impression that others are not important and you can't be bothered.

Thank you.

Jargon: Is it just me or...?

This from my early days working in ISP TS.  Or for those who hate acronyms: Internet Service Provider (the company you pay for your Internet connection) Technical Support.  The guy you ring when something doesn't work like email etc.:

I'm not sure if it's just me.. (surely not) but when I was in school we were taught basic things like punctuation, so you can imagine my surprise to have the following conversation with a fair number of customers - of varying ages so it's not a modern thing - over the 6.5 years I worked there:

Me: OK sir [or madam] please type in 'C [colon] [backslash]'...
Cmr: What?
Me: Can you type in C [colon]
Cmr: What's a colon?
Me: *always VERY tempted at this point to go for the gag but restrained myself*: OK press the SHIFT key, hold it, and tap the one to the right of the L.
Cmr: Oh you mean the double dot [or sometimes dot dot]

Me: *opens mouth*
Cmr: Don't you use your computer jargon with me!
Me: *screams silently in head 'It's basic English punctuation not *bleep*ing jargon!* *closes mouth*

The call generally ended fairly ignominiously but with the problem solved.  Oh and in case you're wondering (as I'm sure you are).  What did they call a semi-colon?  Yes, got it in one. A 'dot comma'.

*sigh*

Education: How Special?

As some of you know I was in Special Education from age 5-12, and at times I have been fairly disparaging about how 'Special' it actually was.  However I think the following puts into context Special Education of 30 years ago as opposed to modern mainstream education.  Before I start though, this is not me against teachers - more about how the standards of education generally have, in my personal opinion, slipped in the intervening years.

At the ripe old age of 35 I decided to do a degree, in Software Development.  I had conveniently forgotten the importance of mathematics, and so the presence in the first year of a module titled Quantitative Methods and Statistics was a surprise and not an entirely pleasant one.  Then things took what, to me, was a slightly strange turn.  The lecturer started going around the room asking students random multiplication questions, and I turned to the guy next to me - who had just come out of A Level Mathematics - and asked 'What's this about?'  His response was a shrug.

I discovered very quickly there was method in her madness, due to the number of students who took a long time answering, or just plain got it wrong.  The killer blow was when she asked a student a couple of rows behind me '7 x 7'.  We waited.. and waited.. the guy next to me - knowing I represented the 'old school' leant over and muttered 'This is ____ing embarrassing!'  I don't recall whether the eventual answer was right or not.  The point of the exercise was obvious.  She wanted to know how much trouble she was in, and how basic she needed to start.  Sadly she had her answer.

You may be wondering what this has to do with Special Education.  Well, when I left Special Education at age 12 I could do up to my 10 times table in my head.  I still can.  In my car I translate the temperature from Celsius to Fahrenheit for fun.. possibly puerile but it keeps my brain active.  These were mainstream educated students on an IT based degree course.  Presumably all had passed GCSE Mathematics in order to qualify.  My questions is how when some of them weren't even capable of simple mental arithmetic?  And standards are apparently better in modern education.

So.. following that little diatribe, let's lighten the mood shall we?  Valentine's Day 2006.  The same lecturer was getting a little frustrated, particularly with one guy on his mobile phone all the time.  As she was writing on the whiteboard it went off again, and I clearly heard her mutter 'Must be someone about a Valentine's card.. they're calling to complain!'

Somehow I managed not to laugh out loud, but she really went up in my estimation after that!

You Called Mummy WHAT?!?

Another from my childhood.  Now I'm not a violent person, but you might think something lurks beneath from the first couple of posts.  Well I *am* mild, unless you upset someone I love, in which case my temper - even as a little un - had, and still has, a blast radius.  This was one such occasion.

I don't recall how old I was, but approximately 10 give or take a year.  I was in (not very) Special Education and it was a sunny lunchtime.  The school was sunk in an artificial dell with raised grass banks - level with the roof of the one storey building - around it.  I was stood on top of one of the banks and a kid - one with whom I had a mutual dislike - was at the bottom.  Now, this little toad had never met my parents but decided to shout at high volume that my Mum was a slag.  [Note to American readers; UK slang equivalent to slut].

Now at this point I walked, with metal calipers up to just under my armpits, using metal elbow crutches, so although I was about 80lbs, I was carrying about 120+lbs with my arms for about 10 hours a day.  Ergo strong little arms.

Well, as a result of the hot temper mentioned in previous posts, a split second after the insult left his mouth, one of my crutches just missed his head, with me following it rapidly down the slope.  At ten you don't think about consequences, but having lobbed a crutch at him, my balance went so I took a controlled crash down the slope, and then stood up.

He yelled 'You nearly hit me then!' to which I yelled back 'I know!  I missed!'  He went a little bit white to be fair and disappeared.  About half an hour later I was summoned from class to the Deputy Headmaster's [Deputy Principal] office.  Now he was a strict disciplinarian who all of us were a bit scared of, but as I was about to find out he was also scrupulously fair.  He asked me 'Why did you throw your crutch at him?'  It never occurred to me to tell anything other than the truth, so I replied 'He called my mummy a slag sir!'  I remember he paused looking at me.  Now I'm not saying I was an angel, but he knew me, and he knew I would never have heard - or used - that word on my own.  So he replied 'Alright.. you can go back to class.. and tell him I want to see him..'  Somewhat relieved I said 'Yes sir' and left.

On my return to the class he was full of venom 'What did he do?  What did he do?' Loving every second of what he thought was my misery.  I looked him square in the face and said 'Nothing.. but he wants to see you...'  I had never before, and haven't since, seen the colour drain quite that rapidly from someone's face.  We didn't see him for the rest of the afternoon.

They say vengeance is a dish best served cold, but the odd hot meal never hurts ;)

And So It Begins..

Or put another way.. 'Start as you mean to go on' :)

(I should first of all advise you dear reader that I have Spina Bifida and Hydrocephalus, net result total inability to walk, plus a couple of free gifts that were on offer when I was born.)

Well.. I was two years old, and in a neighbour's garden playing on the lawn with a group of other children about the same age.  An impromptu Mothers' Group.  Anyway, throughout the afternoon little immobile me is playing with a selection of toys and finding that each one I chose the same little... *thinks* .. boy kept taking off me.  Eventually Mum saw me picking up a little toy cricket bat.

Now at this point I must digress and point out for any younger readers, I am not referring to the modern hollow plastic 'bat shaped toy'.  No, I am referring, essentially to a scaled down real cricket bat, with wooden blade, handle and everything.  Something with a little bit of weight to it, as we shall see.

Mum's last view of me, as she turned away, was of me crawling toward my tormentor with, what she failed to identify as, a determined annoyed expression on my little face.  It appears she was not yet familiar with the temper concealed within the little frame of her youngest, something she was soon to learn.  She says her innocent mind thought 'Oh, he's going to ask him to play a little game of cricket..' and turned away.

Her next recollection is of a swishing noise, such as you might get for example from a cricket bat blade cutting through the air.  This noise terminated - in every sense of the word - in a dull thud of wood meets skull.  There followed a brief silence before the air was rent with an ear-splitting screech of pain.  She turned back to see the victim bawling his eyes out, and her youngest with a big cheesy 'That'll learn him!' look on his chubby chops.  It was at this point she came to the uncomfortable realisation she was sat next to the victim's mother.  However, her worry was dispelled by said mother's comment to her child 'You deserved that.. you've been taking Julian's toys all afternoon!'

Here endeth the lesson.  And if you're wondering.. no.. he never took any more toys away from me ever again *grin*

~THE INQUISITIVE MIND OF A CHILD~

A Poem for Remembrance Day

Why are they selling poppies, Mummy
Selling poppies in town today?
The poppies, child, are flowers of love.
For the men who marched away.

But why have they chosen a poppy, Mummy?
Why not a beautiful rose?
Because my child, men fought and died
In the fields where the poppies grow.

But why are the poppies so red, Mummy?
Why are the poppies so red?
Red is the colour of blood, my child
The blood that our soldiers shed.

The heart of the poppy is black, Mummy.
Why does it have to be black?
Black, my child, is the symbol of grief
For the men who never came back.

But why Mummy, are you crying so?
Your tears are giving you pain.
My tears are my fears for you my child;
For the world is forgetting again.

Anon.
