A doomed flight that killed 10 people in Texas at the weekend seemed "completely normal" before he took off briefly and collided with a hangar, the authorities said on Monday.
Bruce Landsberg, vice chairman of the National Safety Transportation Safety Board, told reporters that air traffic control radar data showed that the Beechcraft Super King Air 350i – carrying eight passengers and two crew members – had been released for their trip to St. Petersburg, Florida was.
Landsberg said. "We do not know any further communication between the crew" and air traffic control.
Investigators picked up a cockpit dictaphone from the crash scene at Addison Municipal Airport north of Dallas, adding that the aircraft was not in operation needed a recorder recording flight data.
Jennifer Rodi, an NTSB investigator, said most aircraft systems had been "virtually destroyed" in the crash.
A Federal Aviation Administration spokesman said the plane had been destroyed by a fire in the hangar. According to Landsberg, two other planes in the private structure ̵
1; a helicopter and a Dassault Falcon 50 – were also damaged.
The flight on Sunday was classified as "personal", so passengers did not have to pay for the trip. The relationship between the passengers and the circumstances of the flight was unclear, he said.
The Dallas County Office of the Medical Examiner published a partial list of victims on Monday:
Brian Ellard, 52
Stephen Thelen, 58
