Why do our clouds have the appearance of wisps? A large methane leak, even in still air, would be wafted by the prevailing westerlies and as methane is lighter than air would rise up, creating what amounts to a WICK in the atmosphere! People can create an explosion by dribbling gasoline along in a line and lighting the end, so the slopped gas acts as a wick. If there's a natural gas leak in a house, someone standing outside lighting a cigarette can light the gas inside the house via this wick method.
Besides, methane burns blue, and THIS also fits the descriptions given by eye witnesses. Remember those movies where punks are amusing themselves by lighting their farts? Cigarette lighter to their rear at the right moment, and a blue flame appears.
