<h1>Aircraft accident investigation intensifies after simulator reenactments show Boeing Dreamliner remained airborne; flight recorders being analysed.</h1> Senior Air India pilots independently ran simulator reenactments of adverse takeoff conditions-higher weight and temperature with gear down and flaps retracted near low altitude-which showed the Dreamliner continued flying; Air India disclaimed involvement. Simultaneously, the nodal investigation agency formed a multidisciplinary team with international technical input and is extracting and analysing the cockpit voice recorder and flight data recorder to reconstruct the flight sequence.
