The guy's a complete whacko. From the article:
They believe the dust must have been contained in a comet or meteor which hit the atmosphere and exploded. There were reports of a big bang in the region at about the right time.
Now THERE'S some real astronomical evidence - a "big bang" noise reported by a few people. Certainly it couldn't POSSIBLY have been a car backfiring or a gunshot or someone blasting stumps in the field. It HAD to be a meteor carrying alien life. :roll: :crazy:
Just as paranoid, but more likely: the government was testing a new biological agent spread by a rocket detonated over the town.
