I personally from the information I have read since about this don't think it was a fireball. If fireballs burn up in the atmosphere then they should be going to ground surely. This definately didn't it was going straight across past us at the same height, even when it appeared to break into two. And each of the parts then carried on the same trajectory each with a blue jet from behind. They didn't split up. They carried on past us even after they had past us at the same height at the same speed in the same direction. I have no experience of such things but how can this be a fireball?

Remarks
This very large object appeared to have two blue jets of flame coming from the back. As it crossed our path it seemed to break into two and each of the fragments had then a blue flame coming from the back. Both pieces followed the same trajectory at the same speed in the same direction until we lost sight of it.
