A put a hole in the side of a helicopter that left it grounded for a week.
I accidentally tapped it with another piece of the helicopter. I’m happily working on helicopters that are made of metal now, so no more of that nonsense.
Edit: also, honorable mention because it wasn’t my fault, but I made a helicopter drop an external fuel tank when it took off… by replacing a light bulb. It was on the button that makes the helicopter drop the external tanks, but there are failsafes so it will only do it in the air. Apparently the internal switch got stuck, so the second the weight was off of the wheels CLONK… and a tank was laying on the active runway. Excellent.

Sounds like it’s working as advertised. Don’t post incorrect info if you don’t like downvvotes. Upvotes mean “more people should read this.” Why do people need to read you being wrong? How is that a good contribution?
