A meteorite, burning with a bright blue colour suggests Copper chloride composition.
Most meteors and meteorites are Iron, which is why they mostly appear to burn red/orange, although Copper Chloride has been found in some meteorites
apparently.
Damage on this scale seems too large to be UARS (which reads as 'You arse' = if we believe it is, we are)
If it was a meteorite, as it seems to have been, it must have been quite a big chunk that entered the atmosphere..remember that most of it's size
would have been burned off by friction before it hit.
So, just how big would it have been to begin with?
I've seen iron meteorites about the size of a fist, make holes about 5x as large in house roofs or in car bodywork...this thing wasn't made or
harder Iron, but copper chloride and "devastated an area 100m in radius"?!
That was certainly bigger than a fist, and could have been as big as a house when it first entered the upper atmosphere!
Remember that most of it's size would have burned off before it caused all this damage!
Why no warning about a house sized chunk of rock and minerals heading our way, when they catalogue objects smaller than this?


) because I think they are reporting on a gas cylinder explosion
that were kept in a garage. The film shows three gas cylinders at (29 seconds in) for some time then points into a garage or room from where I think
it happened.
