That might not be a mechanical breakdown though.
Could quite possibly go down to clean up after someone pukes. That's pretty common.
Well the mechinacs came out and where hitting on one of the wheels or something underneath that railguard (I guess thats what you call it) with a hammer and a mallet. I would say thats a mechincal breakdown.
I really like Top Gun and I think its a pretty fun coaster specially if your smaller and don't really want to ride the big rides yet. I really don't know why people hate on it so much.
^I would like to see any kind of wooden coaster do that. Kings Island tried to bring the new era of wooden coasters with Son of Beast and look what happened to that. I don't see anyone going all crazy trying to break records anytime soon.
