A tourist flight crashes just after takeoff from a remote fishing lodge, killing several passengers. The wreckage layout reveals that neither the airframe nor the engine caused the crash. Now the “Go Team” must launch a probe into the bizarre noises described by the survivors in the last minutes of the flight, and painstakingly determine whether the aircraft was overloaded past its weight limit.

Newcomer Shaun Williams gets a report at midnight of a downed plane in a local bay, but by dawn, the aircraft has disappeared under the waters of Knik Arm. With rescuers and helicopters attempting to recover the wreckage, Williams tries to determine what caused the plane to plunge only two miles before its planned landing. When the fatal crash is pulled from the water, the NTSB rules out mechanical problems, leaving the possibly damaged GPS as the only evidence that might solve the mystery.

A 23-year-old pilot’s Cessna plunges nose first into a public road near Big Lake, and investigator Millicent Hoidal must piece together the evidence remaining from the fiery crash.
