I crashed my P1 by doing a CSC a couple of years back. I was still a fairly new pilot and was trying to maneuver a landing on my case which was sitting on a picnic table. I had just enough experience to be cocky, came in too fast, overshot and then tried to recover before I went into the picnic table. Don't know how I did it but I executed a CSC and dropped into the grass after catching a prop on the table's seat. Fortunately a broken prop was the only damage.
My first flight with a gimble and camera on my Blade 350 was my worst bonehead move...
The bind switch on a Spektrum radio is usually used as a "panic switch" if the RC has "SAFE technology" and pressing it will stablize your flight. I had downloaded someone else's flight program, not realizing that the bind button was programmed as a kill switch... I was about 150 feet up, hit the "panic button" to see how the quad would react, and watched as the quad, my new gimble, and CQ1 camera hit the ground, and several pieces bounced back up. Destroyed everything. I was able to replace the blade body, but had to replace the camera and gimble.
I try not to be so stupid nowadays.
