Ukraine 2002. A Mig 29 was doing aerobatics and failed to pull out of a loop. It crashed into the crowd killing 77 and injuring 543. I made the mistake of watching a video on youtube of that from one of the spectators that day
ah my immediate thought was Ramstein but it didn't look right as i remembered the Italian jet being on fire before hitting the ground.
Russins would have pounced on them if they thought they'd faked it, plus all the astronomers and radio hams.
I think I know the vid you're on about mate, shocking stuff. This is a more SFW version. Still horrific though.
That was another bad one. I used to go to Biggin Hill air shows as a lad, as my brother and dad were aviation mad. Always wondered whether I'd witness a crash there. There have been a few over the years, but fortunately (by luck) none have crashed into the crowd.
I'm not sure I'd even want to watch the 'safe' version tbh. The one I saw was from a spectator with a hand held video camera racing towards the scene of the crash. The aftermath is truly horrifying.
