can someone confirm - If it was a meteorite, could it explode mid air and not cause a impact crater...???

The thing is about it being a comet is that there would be pictures/records of it having been observed by many from all over the world before and right up to when it got here.
But there isn't is there?

Above central Siberia on June 30, 1908, at approximately 7:17 AM local time, a small comet entered the atmosphere from behind the sun and moved in a southeast to northwest direction. The comet was composed of about 30,000 tons of water, methane, and ammonia ice with traces of silicates and iron oxides. Penetrating the atmosphere at approximately 60 km/sec (130,000 mph), the object created an intense shock wave which wrapped tightly around its nose. As it descended that sunny morning, its nucleus exploded (possibly 3 times) approximately 8 km above the Earth’s surface.

If we could heat some rocks up to 44,000 degress F (The heat produced by a fast meteor entering the atmosphere) we could then see if any would explode, but that's hotter than the surface of the sun so not sure we can do that very well. I suppose it's not impossible, but it seems like the comet explanation requires a little less speculation.
