I have included a link to the first interview for completeness - I suspect I have not listened to it.

D.P. Davies interviews

My understanding is that D.P. Davies was the Chief Test Pilot for the Air Registration Board which was later incorporated into the UK CAA. He was for many years in this post effectively the final decision maker on whether to award a UK Certificate of Airworthiness or otherwise. It appears he had a few run-ins with the FAA (indirectly - via US manufacturers who came to him waving an FAA Certificate).

Quotes below were transcribed from the audio for my purposes and may not be accurate. Please refer to the original audio for clarification. I make no comment on the content of these audio recordings and I post the notes here in case anyone is interested in listening to the recordings for themselves and for no other purpose.

No aeroplane should be allowed to pitch up into the stall
Compromising a fundamental principle of stability in the requirements"

"The FAA lacks courage, political clout, all the American constructors can dominate the FAA for political and economic gain and they do."

Edited to add links to the Audio - The RAeS don't seem to make it that easy and I had forgotten that my RAeS links were not to the audio. I feel that there might be more use made of these amazing recordings if they were easier to access. There are I think hundreds of them.
I am leaving the original post in the forum so that I can point the support team to the non functioning links.
