After Sam and Alec return to base from their flight in F-302, Sam's uniform clearly shows an F-302 emblem & her name on her uniform. While talking to Alec, camera switches back & both emblems are missing.
Alec Colson states that over 2000 lives were lost in the supposed meteor shower that took out a US Navy battle group. While literally correct, in actuality the loss would have been over 7,000. The USS Nimitz alone has a crew of over 5,000.
