All combat pilots have their OCD good luck charms, my dad&#x27;s was naming his planes &quot;Round Trip Ticket&quot;. And it did work, they always brought him home, despite sometimes getting holes in the airplane, and various other failures. He has a great picture of the side of his &#x27;stang covered in oil, after it swallowed a valve. Fortunately, it was over the airfield at the time, as the &#x27;stang wasn&#x27;t going very far with the rotating junk that was left of the merlin.
