 MISC: The pilots were not wearing shoulder harnesses, so when the  plane crashed, their heads hit the dash, injuring the pilot and  killing the copilot. (There were also holes in the windshield, but  these could not have been caused by their heads hitting it, because  these windshields are very thick and are made to withstand bird  strikes.) In reality, they would have been wearing shoulder  harnesses, and prior to crashing, they would have locked the  harnesses, so that they would not have to depend on the inertia  reels locking. These shoulder harnesses would have prevented their  torsos and heads from moving forward, so they would not have  sustained these injuries.
