I didn't sleep through it and neither did my children, who were quite small at the time, but my husband did! We live on the Isle of Wight and I remember, particularly, going out into the greenhouse in the middle of the night to check that the rabbits were safe (my husband was appalled that I'd been so stupid the next day), and then sitting, with the boys, watching the power cables arching and sending out huge sparks, like lightning.
The next morning there wasn't a shard of glass left in the greenhouse and the rabbits were upside down in their hutch - looking pretty p*****d off - the fence was gone and the Island was a mass of fallen trees.
I actually quite enjoyed the documentary, I do have to say. If nothing else it made me realise how lucky we personally were that night. We weren't even particularly frightened, just completely fascinated.
