Never flown Eagles either, and my experience in fighting them consists solely of popping flares and praying, but as a fatty driver formerly based at JBER for a long time, pushing it up during a demo is a sore subject for me.
As everyone knows, C-17 pilots have famously fvcked it up many times over the last 30 years. Multiple gear-up landings, multiple departures from the end of the runway, accidently landing at Peter O. Knight instead of MacDill, the four engine flameout in Pakistan... not to mention the missions involving actual battle damage like the crew that took a SAM up the ass in Baghdad in 2003. Some amount of incidents are more or less inevitable after flying thousands and thousands of sorties over the course of decades, but obviously some of these risks are exacerbated by putting young crews in tight spots. Of course, that's ultimately the CC's call, and risk is a fact of life in the military and aviation, especially in combat.
But you know what? Every single one of those guys made it home. After almost five million flight hours across the program, our only hull loss remains the 2010 crash at JBER, where some of our most experienced crew members (an EP, two IPs, and an EL) pushed it up a little too hard at about 850' AGL during airshow practice and put a jet in the dirt. Now every year on July 28, the AD and ANG C-17 squadrons at Elmo go out into the woods and sit around this clearing where there used to be trees, drinking and remembering four of our friends. I'm glad we do it, but I wish we didn't have to.
Full disclosure, I didn't watch the whole video that got posted, but I bet I know what it looks like - it's probably freaking awesome. I was just out at Oshkosh this summer because I love a good airshow... who doesn't? But there's a different calculus and a different set of risks in decision making when one is trying to put on a good show. I can absolutely think of times in my past where someone was watching who I wanted to impress, and I pushed it a little too far and probably made some decisions that I shouldn't have.
No doubt the guy/gal flying this show is a great stick and a damn good pilot. But if we're going to take arguably unnecessary risks in peacetime, we've got to take reasonable measures to mitigate that risk when possible. I've never been a demo pilot, so I don't know what proportion of the AF demo regs are well-thought out vs. pointless bureaucracy, but I do know that the answer isn't to just ignore them all and do nothing, and if that's what happened here, I've got no problem with sacking the person responsible for providing that oversight.
