(Bloomberg) -- An aborted takeoff last year on a US Airways plane in Philadelphia, which smashed down so hard it broke the landing gear, was triggered by the crew’s failure to enter the proper runway into a flight computer, among other errors, according to a preliminary investigation.

“What did you do?” the captain told the copilot as the Airbus Group SE A320 carrying 154 people raced down the runway and its computers failed to display the lift-off speed. “You didn’t load. We lost everything.” His words were captured by the plane’s cockpit voice recorder.

A U.S. National Transportation Safety Board probe found that similar mistakes had prompted other pilots to break off takeoffs in the past at the carrier, now part of American Airlines Group Inc., and at least two written warnings had been issued to flight crews before the accident.
