From watching the movie we know who the main characters of Bruce Willis's roughneck crew are. The FBI national hunt-down search sequence introduces them one by one, until we get to the sequence in the NASA conference room when Bruce Willis gives them the news that the meteor is coming. As we go around the room and each character agrees to the mission, we've got an extra guy. Noonan! He's the one who says, "I can't let you guys go up there alone." He's also seen all through out the teams training and medical exams,(except for the psyche examination, and the Liv Tyler "not a little girl" talk.) Watch for him, he is also the guy who's demands for the government were to have two young illegal alien ladies made full citizens no questions asked. He's part of the team right up until when the shuttle that A.J. is on crashes. Thing is if he died we only see Oscar dead and no mention of Noonan. He's the mystery character that has no purpose in the film what so ever. And if I'm not mistaken his picture is not at the wedding sequence of the movie that are there to honor the dead.
