All the time in the sim..... The first was the most memorable. One engine out on take off and the weather was below mins so we had to divert to another field 12 miles away. Another engine died on the way and the flaps stuck on one side when we were on the approach. Nobody noticed how low we were getting until the screen went red and the everything shook a bunch. Have had the fun of a bunch of crashes doing assault strip landings..... usually just come in, descend too fast and smack into the ground. Near midair the other night, I think the instructor just wanted to show us what the proximity alarm sounded like. The only real inflight problems have been an engine leaking gas and a smallish hydraulic leak.
