The Air India plane that crashed in Ahmedabad on June 12 was a Boeing 787 Dreamliner aircraft. As per a report, Air India had 34 Boeing 787 airframes in its fleet before the crash.

Air India and Boeing are in the midst of significant turnarounds, but knowing the cause of the crash of Flight 171 will take a lengthy investigation.

It could take months to fully understand what went wrong in the crash, the first involving a Dreamliner. Officials from India continued the investigation Friday.
