I know that you didn't go to Cambridge as to Embury Riddie that may or may not be the case. I do know that when you offerred to debate Longitudional Stability by standards one was to do with roll rates and nothing to do with what you wanted. I believe that one of the other standards you wanted to use is to do with ordering spare parts, not exactly stability. I wouldn't expect a graduate from Embry Riddle to make that kind of mistake, its possible of course but it is a basic error

But you did say that Cambridge and others used the Spitfire wing when you clearly don't know

What does your point have to do with that fact or any fact relevant to this discussion?

Because its another example of you making up statements without foundation to support your case.

Or the fact, it is Cambridge University that published the book??

Cambridge University Press is a publishing house NOT a University. The University is an admin for the collages not a seat of learning and supplies support to the member seats of learning, including publishing.

These tend to prove that you trawled for something to support your statement rather than have actual evidence

Speaking of evidence and more importantly, we are all waiting for your source or evidence re piles of bent wings in the BOB waiting for repair. I produced two pieces of evidence you have have yet to produce anything.

You once accused me of being unprofessional so either substantiate your claim or withdraw it, its the professional thing to do

The very first onset is referred to as the the "Buzz" or the "Tickle"

Right, which has what to do with the fact some airplanes have higher energy stall warning's including buzz than others?

Also, what does that have to do with the ability of a pilot to precisely fly to the nibble and precisely back off to smooth air in order to maximize his aircraft's turn performance?

Are you going to have a go at answering the the dive recovery question ?

You saw/have a picture of piles of bent wings?

That would make a cool sig picture!

Not to mention how it would do alot to make your case for this argument!

With that said could you provide me a link to that proof/picture?

Thanks in advance!

If not, and this was just a undocumented statment of yours, no worries, Ill understand the lack of a link provided

There were no piles of bent wings around repair yards in the BOB. The wings only had a problem in late 1944, when being used in situations far beyond those that could have been thought of pre war.

I produced two lots of evidence, one an original document from the NA which is clear on the issue and the solution, the other points you to the C Shores books on the 2 TAF. Both these support my statement and its only fair to ask you to supply evidence to support yours.

With no evidence your statement is worthless.

PS I do owe you an apology.
You said that the design of the Spitfire wing was done at a number of colleges and I asked you which to which you gave me a number. It was a trick question which you fell for.
You may or may not know what is taught at the establishments you named, but you would not know what they use in their lectures unless you had done the course so your list must have been made up.
Also you said Cambridge as one of the establishments. Cambridge isn't a place where you study. Cambridge is in effect an admin centre for 31 Colleges or to be more precise seats of learning and none of them do aerodynamics.

I can tell you that Cranfield is the premier University for Aerospace in the UK its very advanced with their own test fleet of aircraft. We had visiting lecturers from Cranfield come to HMS Daedalus for some of our studies which included Hovercraft

Crumpp, I've never heard of piles of bent wings during the BoB as a result of either pitch sensitivity or instability. It sounds quite extraordinary. Can you supply some references?
