That's what was going on in the pilot's head as he frantically banged on the door. According to the audio, before the crash he is frantically banging on the door trying to open it. News report says the other black box, flight recorder, is missing its memory card and they're searching for it.
ANY NAMES of the PILOTS????
Many airlines have reinforced cockpit doors since 9/11. Perhaps some quickly accessible equipment (locked, with key possessed by trusted crew) capable of breaching such armored doors should be available.
