Tow main things to recall about this particular event.

1/ If any crater was formed it was buried deep in a swamp.

2/ The first scientists to the area took some twenty years to get there. So any real evidence has had a long time to degrade

it isn't unusal for meteors to explode mid air. It is a little unusual (In human experience anyway) for one so large to do it. This is one of the reasons I've been a bit of a comet fan as an explanation.
