In an update to this, after a year long investigation, no clear cause has been found. As best the investigators were able to determine, a problem with
the aircraft led to spatial disorientation.
While other pilots said he wasn't showing the signature urge to get home that can lead to carelessness, he chose to fly the aircraft with a GPS that
would occasionally drop out, and an Inertial Navigation System that would show a weak signal. When they arrived in England, he said the INS was iffy,
but it was "no big deal". The morning of departure he told another pilot if there was weather at their destination he'd have to guide him down in case
his GPS dropped.
He was asked again by ground crew about the INS issue as they were preparing to depart, but said he'd go with it. At 0920, he radioed his flight lead
that he was on standby instruments. The lead asked for clarification but got no response. At 0922 the aircraft impacted the ground.
