Missed Approach procedure will be included in the midair briefing but I dont think anyone ever says here's what we will do if we bounce 85 ft or land with the wheels up. Both events happened to this crew and they must have been shocked to the core.
Two comments:
1. They did not "bounce" 85 feet. The aircraft had a normal (although long) landing and then after touchdown the crew elected (apparently due to company SOP regarding long landings) to perform a go around. Both pilot and copilot executed the go around badly, which had nothing to do with being "shocked to the core." This should have been a fairly routine maneuver using well rehearsed procedures.
2. I agree that no one plans to land gear up. Further, there really is no procedure for a gear up landing other than an orderly evacuation. That they landed/impacted gear up was due to the badly executed go around. The aircraft was fully capable of getting airborne after the long landing and climbing to a safe altitude whereupon the crew could have done a second approach. Sadly, that did not happen. Happily the flight crew was NOT "shocked to the core" after the gear up impact and executed an orderly evacuation.
