Audio recordings of a conversation between an air traffic controller and an airline worker that stole an empty plane from Seattle's airport shed light on the final moments before the stolen plane crashed on a remote island near Seattle on August 10. An Horizon Air ground service agent took the controls of a Bombardier Q400 turboprop airplane in a maintenance area at Seattle-Tacoma International Airport at about 8 p.m. local time Friday and took off, embarking on flight over Seattle before crashing about an one hour later on Ketron Island in Puget Sound.
