This airplane did not bounce!
Now that the scenario of this long landing followed by a go-around from wheels on the ground is better understood it is very clear that this airplane did not bounce. The crew took the deliberate action to fly away from the ground.
Climbing 85 feet starting at a typical landing speed translates into a loss of approximately 10 knots due to transfer of energy from kinetic to potential. This could well have brought the airplane close to stall.
It would be very interesting to see actual time history data for speed, altitude, and throttle position. Did the crew recognize the lack of power and push the throttles forward before reaching their max G/A altitude of 85 feet? My guess is that they did not and were already headed for their gear up impact when those precious 12 seconds had passed and they finally followed up with the throttles.
