Considering your screen name, Jack is very lucky, because this should have been a smoking hole in the ground.
Just a couple of points:
based on amateur video it has seen, Roush apparently overshot the centerline of the runway and made several course corrections.
When he overshot the centerline, that is when the decision should have been made to go around. It was a major overshoot according to witnesses as it put him over the crowd and heading for the tower. Over the crowd is relative, because the airshow had been over about 15 minutes by my guess or the “crowd” would have been in the thousands. He was so far off the centerline of the active runway that the runway and taxiway were on his left, and as seen in the pictures, he is angled even further off centerline toward the aircraft parking and spectator viewing area.
My wife and I were in the Flying Magazine booth when she said “whats that”, I looked up and said “I don’t know” wondering at the moment if she was wanting to know type aircraft, or why it was visible and doing steep turns a hundred feet off the deck. The second turn observed, was decending, and I knew then the airplane was headed for a crash. The crump was heard a couple of seconds later, and everyone knew it had crashed. The next words out of my wife were, “where is the smoke”. Of course milliseconds after the crump usually follows the first explosion.
Miracles happen. and in this case, following the one in Alabama nine years previous, even more so since the engines apparently kept running for a considerable time after the crash.
Where was his actual touch down spot? By the looks of the classics in the parking areas of the photos, was he just north or south of the Ultralight area when he hit?
