"We just watched and waited until the crew checked into their hotel", Popovich says, "then we grabbed their plane and flew away."
That certainly doesn't sound like they're doing a lot of inspection to ensure a safe return. Granted, it's only their hind-ends and they are aware of the risks, but I think this guy and his crew certainly deserve a brass balls award.
If my experiences with my own (single piston engined) airplane are in any way representative, I would be surprised if the first flight out of major maintenance isn't statistically significantly riskier than a random repo flight.
