I understand it went down due to mechanical failure/hard landing, not from hostile fire. It was destroyed in place, probably as soon as the Team exfilled.
I wondered about that when I read it was bought down by hostile fire but everyone escaped injury. Unless a lucky shot brings down the bird, enough hostile fire to down it would mean likely casualties, let alone trying to land a damaged chopper under fire and have everyone remain unharmed.
I then wondered if it was sacrificed to support the story OBL was shot in a firefight while resisting capture. Only matters to the PC folks...getting him dead was the goal.
Same with the full ceremonial burial at sea. Making sure the body was never found was the goal and it doesn't matter if it was tossed out the door as soon as they were over deep water.
Professionalism was maintained and no dishonor was committed.
