No pictures (maybe a good thing) but in Westminster, CA there was a BMX track (can't remember the name) my best friend and I would ride to from our neighboring Cypress. One day in about 1980 we were pedaling laps around the track, building confidence on the bikes we brought that day. At the beginning of the track was the standard downhill portion, and when you make a full circuit and come around to the start there was the huge flat-top jump where you can air it out and land on the downhill ski-jump style.
My friend Mike was riding his full-fendered post war Schwinn B6, and he aired it out max speed, springer and all. In mid air his front rim flew off, and I will never forget how his forks touched first and dug in quite splendidly, launching his whole being over the bars. He and bike tumbled a bit and came to a stop, as did everyone else within 50 feet. Helmet? Nope. Pads? No. He was OK except for some nice raspberries, the bike not so much. Forks wasted, bent frame, "W" shaped front fender. I believe he hobbled the bike together and I rode him some of the way back on my handlebars with him holding the bike which only worked for about 100 yards. We walked the rest of the way home a little wiser. Klunkers from now on if on the trail or track, and give your bike the once-over with a wrench before flight.
