Saw just a real short clip of something on the Disc channel tonight
about how methane clouds affect aircraft. Lower pressure causes the
plane to drop because of reduced lift, and the altimeter to read a
climb because of the pressure change. I think this show may have been
in the context of bermuda triangle stuff. Maybe Im just out of the
loop but I had never heard of this happening (flying into a cloud of
methane I mean). They seemed to have some pretty reputable people
talking about it. Anyone experience this or hear of it?


Martin,

It's a theory that's been "floating" around for some time, but mostly
regarding it's effect on ships.

They've modeled the effect of a methane mega-bubble on bouyancy and have
shown that a large ship would basically drop like a stone if it were to sail
across such a bubble. Hence no SOS, no life boats, no sign of ship or crew.

I'm just guessing, but I'm pretty sure there would have to be a similar
effect on an aircraft due to a decrease in air density?

FWIW...
