But they didn’t have a lot of time to ponder that one I suspect. If you are so overloaded as to land halfway down the runway with the gear up at high speed, I suggest that there wasn’t a lot of thinking space left?
The main issue here is why did the Crew of the plane not observe the landing gates which are there to force a go around long before it becomes a crash. Been an SOP for years and in well run airlines it’s mandatory and there’s a no blame culture for executing a go around at any stage when the approach is becoming too unstable to safely continue.

Another logical assumption emerged by a A320 pilot:
There was no issue of L/Gs, L/Gs were down during 1st attempt.
G/A was opted to avoid runway overshoot due to high altitude approach leading the acft to 4500 ft from threshold.
Now this is the catch:- Probably Flaps selection to position 3 from 4 and Gears Up selection was too early while engines still spooling up from approach Idle to TOGA,.
Too early retraction of Flaps caused loss of lift and acft sank while the Gears already retracted up and engines dragged along the runway 3 times( as witnessed on runway)
First mark : Eng 1
2nd mark: Eng 2
3rd mark: Both engines
Acft climbed with struggling engines to 3000 ft but couldn't hold the Alt and ATC warned the crew about this and crew asked for 2000 ft but due to complete loss of power acft kept on descending and crashed on to residential area.
Pic taken by plane spotter shows dragged engines with black marks and RAT auto deployed due to dual eng failure( AC Bus 1 & 2 being dead ).
Having lost G&B Hyd crew extended the Gears by Manual Gravity Extension, L/Gs extended can be seen in the video just before crash.
Aircraft was still maneourable as Flt Control being supplied by Blue Hyd circuit pressurised by RAT and Flight Control computers by Emergency Generator but no power to keep the acft up.
