The U.S. Air Force drone, on a classified spy mission over the Indian Ocean, was destined for disaster from the start.

An inexperienced military contractor, operating by remote control in shorts and a T-shirt from a trailer at Seychelles International Airport, committed blunder after blunder during a six-minute span on April 4.

The pilot of the unarmed MQ-9 Reaper drone took off without permission from the control tower. One minute later, he yanked the wrong lever at his console, killing the engine without realizing why. As he tried to make an emergency landing, he forgot to put down the wheels. The $8.9 million aircraft belly-flopped on the runway, bounced and then plunged into the tropical waters at the airport's edge, according to a previously undisclosed air force accident investigation report.
