Quite simple, really. When the Maine blew up in Havana harbor there was a large amount of coal dust ejected from the bunkers. This cloud of superheated coal dust then went directly to the upper atmosphere, where it remained energized by cosmic and solar radiation. It wasn’t until 1908 when the cloud descended, en mass, over Tunguska, that the particles of dust would be able to combust when the static of the cloud generated a spark.

No, no, no. Tesla provided the spark.
