Could this be the explanation for the non-radioactive mushroom cloud seen by airline pilots in the Pacific one day in the late 70's - early 80's? It was never connected to any source that I am aware of. Some theorized it was caused by an undersea volcanic explosion, but no one succeeded in associating it with one. It was not a nuclear explosion, although some at first suggested that. It is unlikely to have been a non-nuclear explosion, ie no ships disappeared and I'm not sure I see a motive for an experimental blast in that part of the world. Just a thought, although I would not expect a mushroom cloud from such a comet strike. I'm not sure I can even see a mechanism for creating one from a Tunguska class strike.
