tailstrike on an A320-200 occurs at 11.7 degrees oleos compressed, and 13.5 extended. The data recording rate for pitch is not particularly fast, nor is the WOG discretes, so a rapidly pitching aircraft can record very high values without actually touching its butt, but they were close, really close. Pitch rate would have been impressive, but is possible, the elevators are in a direct law at that time. Pretty interesting ride for the pax. The flight crew got to have an unusual view of the runway on the third impact, imagine a face plant. That the plane stayed in one piece is remarkable, they were well outside of any design criteria, the loads would be extraordinary, and I would think that there will be a long long long inspection on the aircraft after this one.
The 3rd impact is consistent with a PIO in the bounced landing recovery, which is why the procedure that is written by Airbus and Boeing and everyone else is pretty clear. These guys were lucky. The damage to the #1 engine is impressive in its own right.
Lottery tickets for all, and the airline.
