DA Henriques. I, like Treadigraph, witnessed the P.38 accident. I also heard of the theory re the kneeboard and the yoke interference. However, talking with Steve Hinton at Oshkosh shortly after, I asked his opinion. Apparently, in Steve's opinion, he pulled the first roll [yes, there were two] too early, and realizing his error, went for the second one with too little pitch and speed. He made the point that Mr. Proudfoot was red in the face with anger just before his display, as the BoB Memorial Flight had completely cocked up the timing of his and others displays. As Steve said, that is no condition to go to fly a tight display, and he felt that it was this state of mind that was possibly the cause of his misjudgement?. Who really knows. It was a very, very sad day. I have read your posts with extreme interest. Many thanks for them.
