Its great until you realise that unscheduled plane dive-bombing below legal levels just put someone's child in hospital.
If it's bombing a built up area, that's a bit naughty, so you'd probably be OK to shoot it down. Perhaps he was lost and though he was over Dresden?
I'd have thought it's pretty unlikely though... the Spitfire is a fighter (and as far as I am aware, didn't carry bombs - though I will accept that I could be wrong about that) and I've not seen anything on the news recently about a Spitfire doing any bombing in the UK.
Were the bombs making big craters?
If unscheduled bombing causing injuries is not on, is it OK if they schedule it?
