A four-part series of the interview with one of the greatest test pilots, D. P. Davies, conducted in 1992 for the Royal Aeronautical Society. Almost five hours of avgeek gold. (The other three parts should be listed at the bottom.)
D. P. Davies is also the author of the seminal work about flying large airliners, "Handling the Big Jets".
Although less well known, he is undoubtedly on the same level as Chuck Yeager and Bob Hoover.
The level of expertise and adventure, combined with the British humour and understatement, makes this immensely enjoyable to listen to, despite the less-than-perfect audio quality.
