What happened

The main wreckage was located two days after the accident, featuring approximately three feet of the tail boom still attached to the primary structure. The deformation observed on the wreckage suggested an uncontrolled impact with the water. Following the initial recovery, a middle section of the tail boom was found floating roughly 60 miles from the main wreckage site five days later. Fifty-eight days after the accident, the aft-most section of the tail boom was discovered washed up on a shoreline.
