Maybe some cold war secret bubble weapon !
Yeah, maybe methane escaping from sea bed.Or other gases.
Some peeps think Bermuda Triangle 'mysterious disappearence's may be due to this (although that doesn't explain aeroplanes ).
I'm sure I read something about that in New Scientist maybe last year.
I'll post again if I find the article ( don't count on it,as I don't know where all my back issues are)

Well, according to the article, it says that these gas bubbles 'had the potential to cause aircraft to crash'.
Yes, I think methane is less dense than air, so airplanes can crash if they suddenly hit a columun of rising gas from the ocean floor.
Oh man! That stinks!
