And there was the time that I was on the return run at Bonneville, after having changed the oil in impound. I (evidently) didn't tighten the filter enough, and when I was about halfway down the course, on the nitrous button, the loose filter spun part way off, allowing the oil to go away. About five-ten seconds is how long the engine lasted after that. If I had had safety wire on the filter the cannister might still have been loose -- but most likely wouldn't have worked so loose that the oil got out quickly.
I now vote for wired oil filters each and every time.
