Pilots survived and already answered questions - they decided to land because all systems started failing after lightning strike, not because of fire - there was no fire before landing.
I didn't claim otherwise and yet the point still stands: as far as it is known the was no visible fire. only the final report will establish the absence of fire. can't really fathom how people can't tell the difference.
if you talk in terms of "proof" the videos tell there was no fire visible before the third bounce.
sure it's more likely that there was no fire as opposed to a contained fire, but you need to split what video proves and what video suggests.
