At my flight school, one of the instructors decided to do an engine out test on a student on a cross country. He did this by really shutting down the engine. Now, he wanted the actual shutdown of the engine on this 152 to be a bit of a surprise, you know... for better training. I'll also note that it was a commercial student, so he already had a private pilot's license.
In his infinite wisdom he decides to use the mose inconspicuous item he can think of... the fuel shutoff valve which is between the seats on the floor.
Most of you probobly already know where this is going.
I had a really long story written out, but the cliffs version is... now there is a 152 somewhere at the bottom of Watt's Barr Lake in Tennesee. They never did find the plane after it sank. The student ended up changing career courses and is an airport manager in Texas now. He couldn't swim at the time and was fairly traumatized by the whole thing.
For the most part the stories that I have, and will admit to

, aren't all that exciting.
I can tell you that taking over an hour to deice because deice trucks kept breaking was a bit amusing though. That was just last week. Probobly don't want to know how much money that was in wasted fluid trying to get that done, not to mention the fuel we burned.
