I am fortunate to have seen him fly on many occasions and talk with him on several more. He used to give forums at Oshkosh where he would present a slide show and give commentary on each photo. I wish some of those were available on DVD. There was a tribute to him a few years ago at Oshkosh and most of the now recognizable names in aerobatics made comments in the event program that they could not do what Bob did in his show, even though it just seemed like run of the mill loops, rolls and such. It all drastically changes when you switch the engines off! The late Bob Odegard did do a "Energy management Maneuver" but did not put it on the deck like Hoover could. He did shut down both engines, did a loop, roll and land and taxi back to show center, all dead stick. If you can find his book, buy it and read it. He's probably the best stick and rudder guy that ever flew.
Type at you later,
