Had one retract his flaps as soon as he touched down in a crosswind one day...but he grabbed the wrong switch and the squat switch was on the other gear leg and it came right up.... his brother really rode him about how stupid he was....guy felt terrible. Long story short, new engine, new prop, lots of new skin on the belly and a big engineered repair on the lower spar cap, and it was back in the air. We'd said there was a switch guard that could prevent that, but the "smart" brother said the dumby had already done that so it wouldn't happen again. The "smart" brother elected himself to fly it from Kalispell, MT to Polson, MT on it's release from the shop....you guessed it.... pulled the gear up in another cross wind. Less than an hour flight time. Guess he wasn't so damned "smart" after all. The other brother never said a word, but you could see him trying not to laugh when he told us.
