It was amazing! It must have been really big and/or really bright because it created shadows on the street and the delay between the first shadows appearing and the delayed boom was maybe more than a minute.

Remarks
The fireball was behind me and I noticed it because it was so bright it illuminated the street and created shadows on the road from the overhead powerlines. It took me a few moments to realize this was unusual and I looked up in time to see the fireball fragmenting. It seemed to break up in 3 main components (all in line with the fireball\'s trajectory) that then individually disintegrated.
