Some problems with this explanation
1) it's not that rare for natural gas to be released from the bottom of the ocean. Why is it that only at the Bermuda Triangle do this cause ships and planes to disappear?
http://www.whoi.edu/oceanus/viewArticle.do?id=2441Even the article itself says methane is also released in the North Sea (that's between the UK and Norway), and the Sea of Japan. Why don't planes and ships disappear there as well?
2) if a large bubble of methane breaks the surface of the sea, continues to rise, and envelopes the area around the plane, it might kill the engine due to lack of oxygen. But planes can glide even when all engines are stopped. Pilots are even train to ditch the plane in water. And they float. The planes, not the pilots. Although some of them may float too.

4) i cannot see how it affects the buoyancy of ships
5) if a plane, flying at say 200km/h, at an altitude of 2000m hit one of this newly risen methane bubbles, and it's engines all stop, it should continue to glide until it gradually loses all altitude. In one minute, the plane should have travelled a distanced of 3km. How big are these bubbles anyway. Couldn't the pilot have restarted the engine as soon as the plane exits the bubble.
