We had a detachment of two Marine NOGs a/c attached to our squadron for evaluation and testing. One night, on a mission with one NOGs a/c and two of our a/c, the NOG got an engine shot out just as it got to its target.
As luck would have it, the Major in charge of the det had just arrived in the bunker for a later flight. When the young 1Lt called in with an emergency, the Major took the radio mic. He told the 1Lt to put away his NATOPs and his emergency procedures. He then proceeded to slowly read the emergency procedures to the pilot, told the #2 a/c to stay back and quiet, and told the #1 a/c to call the tower to declare an emergency and clear all arty.
He went thru everything slowly and step by step, including to tell the other two a/c (ours) to be sure to stay above the NOGs bird so jettisoned crap, including all of those live 20mm rounds being pumped out from the Gattling gun, wouldn't hit them.
He was calm, organized, and totally in control. All he wanted the Lt to do was fly the aircraft. Don't think, don't talk, just fly.
It was a great example of someone stepping up and taking control.
