If the fireball was seen from Maryland to Boston, that must have been a BIG chunk of rock.
You'd probably be shocked at how tiny the rock really was.
1) These things are moving at incredible speeds
2) They are incredibly high up, probably 20 times higher than they "look." When one of these disappears from view over the horizon people will absolutely insist it must have hit "just over the next hill" when in reality it never got closer than 60 miles to the ground.
