An American Airlines pilot was heard frantically declaring 'mayday' just moments after takeoff in harrowing air traffic control audio.
The Philadelphia-bound flight had departed Boston Logan International Airport at 6.45pm on Sunday but was forced to turn around after just 10 minutes as the 2013 Airbus A321-211 suffered multiple failures, flight data shows.
In air traffic control audio, the pilot could be heard telling air traffic control back at Boston that he was lowering the plane from 8,000 feet in the air as he declared an emergency.
'Mayday, mayday, mayday, American 2616,' the pilot said quickly.
'We need to return back to Boston,' he continued, explaining: 'We have a loss of the autopilot, loss of auto-thrust and we have a position disagree[ment] between both of our [flight management systems].'
He later emphasized: 'We have multiple failures, including navigation and automation as well.'
The pilot also informed the air traffic control that there were 200 'souls on board' the commercial plane and it had 237 minutes worth of fuel.
The pilot ultimately needed guidance from the ground to land back at Boston Logan International Airport, but was able to do so 53 minutes after its original departure.
