Not interested in a Garmin 196! I did lock it and it's not only that the
lock was broken, but the door was left hanging open. I would assume that had
I left it open, the guy that fueled it would have closed it, or at least
made a note of it.


A thief who didn't find anything interesting after he broke in? A
bored kid breaking stuff for kicks? Maybe you forgot to lock it, or
it came loose (airplane locks are usually too reliable), and the door
came open....

Unlikely as well that they wouldn't see someone in it. Assuming the door
was still intact in the morning when they fueled it, that meant it didn't
happen overnight. Had to be in broad daylight. Doesn't take much to break
the lock but in broad daylight and then not taking anything? Maybe whoever
it was thought they got caught and took off. No proof one way or the other,
that's one reason why I didn't say anything to them. Bored kids usually
throw stones at windows and such.

It seems really unlikely and FBO is going to break into an airplane
just to get your name! Most everybody knows how to look up owner
names and addresses from the online FAA database.
