Drone police hat on but it’s this kind of flight that gets the attention of the haters in the UK.
You were flying against UK drone regs in so many respects that you’d have been bang to rights if you’d been collared.
Flying over built up areas of London and we’ll outside of VLOS is asking for trouble. Sure most of us (me included) do the odd cheeky flight but try to use some common sense. Crashing into a building close to the railway is edgy to say the least.
Glad you got your drone back though and there’s some excellent drone repair companies in the UK or even give it a go yourself.
