The pilot is the captain of the ship. In his hands he is the boss. As far as the 2nd Amendment goes he's the only one it applies to, because it is a private plane. As long as the ships owners turn the ship over to him, he is the captain. He has the right to determine who is armed, and who is not. No one else has that right, including the govm't. A gun if he so chooses, is his last line of defense.
Cool heads and gun control result in disasters like that which occured on 9-11-01.
We are already trusting our lives to the captain, and it would save a great deal of money on sky marshalls! ARM OUR PILOTS!
