Ah, Tim! Perhaps we should have come to you first…
Very best wishes

Hi Proctor,
Yes, I see what you’re driving at with regard to turning moments…just out of interest, have you considered actual rudder authority of the types or are you taking guidance from SOPs?
I do find these sorts of discussions interesting because I like to run ‘what if’ scenarios when flying…I’m but a humble T6 instructor but my friend has a couple of hundred hours on Spitfires – we had a chat this morning and his take on it was that if there was any doubt about the integrity of the wheel, a well executed gear up landing would be safest and limit damage, though if it was a simple flattie, a landing into wind on concrete would probably work.
Just a quick edit – post 24 was still considering the normal situation with a 170 and why a Spitfire would be considered to have a narrow track whereas others are not.
Assuming a skilled pilot…and the undercarrriage leg doesn’t bite into the grass:)
I think Spitfires / Hurricanes did fire ‘explosive’ 303 (7.7mm) ammunition during the Battle-of-Britain but I’m not sure if it was common.
Was it not the de wilde ammunition that gave a flash on impact? I’d be surprised if there was explosive .303 ammunition…
The other thing is the energy in the system…if we think of kinetic energy (1/2mv squared), an increase in mass and velocity means a significant increase in total energy. Since the heavy taildraggers have much greater energy than the 170 or Tiger Moth (as do the small taildraggers like Pitts Specials, with their high high wing loading and high landing speeds), that energy must be expended somehow…Hopefully it’s just a longer landing roll, but if control is lost or there is sideways drift, that energy is working behind the c of g to swap ends, the infamous ground loop. It can happen with balletic grace at low speed(I had it happen to me in a Cub once, and the Tower assumed it was a graceful manoevre executed to leave the runway expeditiously – they couldn’t have been more wrong, at that point I was just a passenger) or with metal bending violence, which would be the case if a wheel dug in on touchdown in a heavy taildragger.
So I think that total energy plus comparitively narrow track would be why the Spitfire ( and Bf109) would be considered trickier that a Hurricane or P51 etc, and all would be more of a handful that a light, low wingloading taildragger such as the 170 or Tiger Moth, assuming same wind conditions.
Cheers
Perhaps not a narrow undercart per se, but certainly when compared to the Hurricane, P-51 etc. The problem with a taildragger of course is that the centre of gravity is behind the mainwheels and so they are inherently directionally unstable as opposed to a tricycle gear where the forward c of g means that is will tend to self correct if the a/c lands with a bit of drift on…a wider undercarriage is certainly a desirable feature on a taildragger, not nearly so significant on a nose wheeler like the 172.
Using published figure then calculating VSo * 1.3 gives you 85 mph for the Spitfire IX as against 120 mph for the P51D
I suddenly know which I am preferring.

120mph is a reasonable approach speed but actual touchdown is around 90mph, still a fair old lick. If you knew the tire was u/s ie spotted by wingman, then a gear up landing might be the safest option.
“I think someone’s been having some fun with you…”
The Corky Fornof incident is extremely well-documented, by a variety of newspaper and TV teams that quickly went to the scene as soon as a few phone calls were made, and is quite well-known among U. S. aviation people, though apparently it didn’t make it to the UK. Say “Corky Fornof” to just about any pilot in the U. S. and they’ll either respond “Bearcat” or “that Interstate landing.”
A little very primitive searching should turn up for you a number of news reports and photographs, I should think.
And yes, the incident was in effect reproduced for the Bond film, since it predated the film.
Hi Stepwilk
I posted after a few beers last night, I hope I haven’t caused any offence…Your tale did seem a bit fanciful, not the landing itself but the calm insouciant ‘Fill er up please…”. Despite the movies, witty banter is not usually the first port of call for those who have faced death in the cockpit and got away with it. So I did a search and I found the story related as you describe but as to the punchline…
“Actually, I made up the last sentence, but he might as well have…”
I know journalists and pilots love a good story and this is certainly one of those, though clearly a bit gilded for effect. No problem with that, but since you seemed a bit miffed by my response, I thought I’d tidy it up a bit.
All the best

By the way…film? “Always”…Catalinas, Invaders, a bit cheesy but a lot of fun.
Hehe Stepwilk,
I think someone’s been having some fun with you:)
Stores probably had a surplus of black paint.
Well, I’ve met them a few times. Appears they had the rug pulled from under their feet when the hangar at Goodwood was closed down. They don’t seem the types to take others money and head for the hills.
as USUAL -having taken folks cash with no flight & no return!
Is this a fact?
Are there really BoB deniers – like holocaust deniers? It never really happened……:confused:
I think that quite a lot of Germans would deny it happened…I believe it’s viewed as a minor skirmish by many, a prelude to the major events on the Eastern Front.
But then they would, I suppose;)
I believe they lost the hangar at Goodwood and have suspended operations…
