I have a private pilot license, and three of us flew out somewhere for the day. I'm asked if I can give someone a ride home but I can't, because I have to go to work in the morning. Even flying, it will take so long, and I need to sleep at least a little. But they won't let up so eventually we take off.
During the preflight checks I find a bag with a person in it. This person is revealed to be Michaelangelo, the ninja turtle. He doesn't know how he came to be there and is very scared, so I agree to take him home too.
Shortly after takeoff it occurs to me that I don't know how to fly an aircraft actually and we are forced to attempt a landing on a busy highway. Exciting!
