True altitude peak
Has anyone been able to determine the true max AGL altitude reached?

loud bang?
Its like the lift was sucked out of it! Looks like a overloaded 172 trying to climb out a valley towards rising mountains on a hot summers day.
Was the take off weight entered wrong? rotate too soon and nurse it along? The rotate and initial climb looked normal for the first couple hundred feet though What could cause a loud bang on climb out? - Compressor stall - Engine failure - Load shift in aft cargo hold It really is a mystery 787 drivers - How would autothrust typically function? What would an impaired airspeed indication/sense look like? Subjects (links are to this post in the relevant subject page so that this post can be seen in context): Engine Failure (All) |

Weight on wheels
What if they tried to select gear up and nothing happened due to some software glitch? I presume the gear will not retract if the WoW switch is closed? What about the TOGA switch will that work \x91on the ground\x92?

The complex software.
Can anyone familiar with the 787 built in overspeed protections comment on what could possibly override a pilots TOGA button command or fire walling the throttles?
I am presuming that at some point just prior to the mayday call the pilots would have just commanded \x91full\x92 thrust and received no or a significantly mild response. I don\x92t think fuel contamination, birds or anything else external to the aircraft affected this crash. There is no evidence of it. could some combination of already MEL items and one or more faulty inputs to the computers cause the aircraft to \x91protect\x92 itself into the ground? Regardless of throttle position? I am thinking - ground/air logic, faulty airspeed sense, faulty AoA sense or other.

The trouble I have with that theory is the there is nothing routinely toggled while flying in that throttle quadrant area on a 787 or 777. It is fuel or stab cut off/out. Especially so at such a critical phase of flight. Has it been confirmed if there was a jump seater or not on this flight?

Are you sure about that?
Is it time for a \x91are you sure about that?\x92 Prompt for select serious config changes?
My computer asks me that when clicking \x91delete\x92 on a file. the way everything is integrated now - the airplanes are pretty good at knowing what\x92s \x92normal\x92 selecting cutoff on the engines while in ground mode could be considered normal, but while flying it could sure use a second verifying prompt.
