I really didn't like the link Socialist posted. Many of you know I'm retired Air Force. Even though the Blue Angles are Navy they flew out of my base in Arizona for a demonstration flight. I was impressed by their skills. Every single maneuver is somehow used in combat. Close air support was a key factor of keeping the troops alive on the ground in Vietnam. Yes, demonstration teams are show. But, they are necessary to generate public support.
When I was in Southeast Asia (Vietnam) as a maintenance technician on F-4s a photograph was sent around. Our base had two RF-4s flying in formation when one exploded killing all aboard. Their cameras were operating at the time. The picture from the surviving aircraft showed a SAM missile about 20 feet from the tail pipe of the exploded F-4.
Oh, the straight up, afterburners burning is a technique used to avoid missiles. Our pilots are trained on that and many other maneuvers. For the show they burn a smoke train. In war they don't.
I really hate it when people who have no idea profess to be experts. I'm from the Midwest. This is just another reason I don't want to go to Seattle.
P.S. The sound? Why don't you ask a veteran who was a grunt in Vietnam in a fox hole what that sound means. It means survival.
