 MISC: The pilots were not wearing shoulder harnesses, so upon  impact, their heads went forward, striking the dash, injuring the  pilot and killing the copilot. (There were also holes in the  windshield, but these could not have been caused by impact with  their heads, because the windshield is very thick and is able to  withstand bird strikes.) In reality, pilot wear shoulder harnesses,  and prior to crashing, lock the inertia reels so that there will be  no slack, thus preventing their bodies from going forward upon  impact. In this crash, the shoulder harnesses would have prevented  these injuries.
