A Boeing 787 Dreamliner landed in Birmingham, United Kingdom, this past weekend with an unexpected complication that alarmed the Air India crew flying flight 117. The plane touched down with the ram air turbine (RAT) deployed, unbeknownst to the flight crew.
The pilots and cabin crew of Air India are especially wary of any malfunction aboard a 787 Dreamliner after the fatal crash of flight 171 in June that saw a catastrophic loss of life. Following the incident over the weekend, the Air India crews are demanding all 787s be grounded.
