A similiar show (or maybe the same one) I saw where they injected a stream of bubbles under a boat and caused it to sink.
Methane hydrate will burn at room temp (fire ice) and will fizzle like an alka-seltzer if it’s disturbed by an earthquake and gets dislodged bringing it closer to the surface. It can cause enough bubbles to sink a boat. I assume as it rises through the atmosphere it could cause engine failure in an aircraft.
Didn’t Mythbusters do this?
