If you listened to the videos, though, you can hear what sound like air defense weapons.

Any ideas about what sort of size this was? Smaller than Tunguska?
Most likely, this was stony meteorite with very low volatile content.
... Still nothing on the impact site or about any recovery of material.
>>Any ideas about what sort of size this was?The energy release depends on velocity and angle more than on the size. Without such info, it could be anywhere from kilograms to hundreds of kilograms.

People tend to sneer at 'what if...?' scenarios but I think we'd be talking about the first confirmed direct mass fatalities from a cosmic collision this morning if it weren't for the fact this shower was over a sparsely-inhabited area.
although I'm sure there's a silicate or metallic core around which the object formed.

Are you sure it was volatile-low? I would have thought that there would have to be some kind of volatile content to act as 'fuel' for the final detonation, although I'm sure there's a silicate or metallic core around which the object formed.
