Let's also not forget that Habsheim is essentially a field for light and general aviation a/c. The runway certainly isn't long enough for an A320 in normal operations and this was also factor in the accident. Many who watch the video think that the aircraft was demonstrating at an airfield it had taken off from - it hadn't.
If this fly-by had been at an airfield with a long enough runway for a big jet, and one clearer of obstacles at the end than Habsheim, then he'd have had time to fly out of it before hitting something....
Looking at the crash footage it seems a miracle that anyone got out alive - as it was I recall there were only one or two fatalities, but that's too many considering this was an entirely avoidable accident!
