This has bothered me for a long time. Not only pilots, but also spectators, are killed in airshow crashes. I could never understand why pilots feel compelled to fly old fighter planes or other very old planes just to show people that they can fly. If a 737 crashes, that's horrible, but there are lots of other 737s around the world. If a Mustang P-51 crashes, that plane is gone forever. All sorts of rare, impressive planes have been destroyed in crashes during airshows.
What prompted this was a report on another fatal crash a few days. ago. A 22-year-old(?) woman was flying a Grumman AT-6, and it crashed. Both she, her passenger, and the plane are gone forever.
Another video explained the crash of an old fighter from the Spanish air force. It was "original not restored." I wasn't able to find that one again.
A third example is different. A 1939 JU-52 tourist plane crashed in Switzerland. It turned out that the pilots for the company were daredevils, and they didn't follow company policy. The fleet of JU-52s was poorly maintained, and examination after the crash showed that the airframe was deteriorating. The company made lots of mistakes, and a crash was inevitable.
Here's a comment that many of you won't like, but I've heard it in several crash investigations. Military pilots sometimes take unnecessary chances when flying commercial airliners. In the military, the goal is to get the job done, but that doesn't apply to commercial aviation. They will do whatever it takes to complete the mission, which is great in time of war. In commercial service, pushing through in bad weather or continuing on with a damaged plane isn't necessary. In the JU-52 example above, both pilots were ex-military, and they relied more on their military training than flying safely. They got themselves into a box canyon at a low altitude, something they had done many times before, but this time, updrafts and downdrafts put them into a stall.
Rather funny - The narration in the JU-52 crash was done by a computer, and when it came to "JU-52," owned by JU-Air, it pronounced those words phonetically. We would say "J" "U," but the computer saw it as a word. It sounded all right, sort of, but it was funny seeing how the CC put it onto the screen.
