Awesome arn't they!!??
Saw two smaller burn up's last night whilst out.
Have only seen 1 like yours, really top stuff.. I also thought mine was an aeroplane. I thought it was a jet doing an after burn dump. Was it travelling parallel to the horizon or coming in at a sharp angle?
Add the time and date, to your original post and you have a logged searchable record, which may assist others googling for it too.
