How my first drone, a Mavic Air, met its end 
Subtitled “Why you shouldn’t get fixated on the camera view, back into a tree, and crash into Lancaster Canal”
I’m not sure what is in canal water, but it certainly killed the drone - sold for spares and proceeds put towards an Air 2
Drone killing lurgy.
Sorry for your loss 
No worries - my own dumb fault 
Onwards and upwards - the Air 2 is great, as is the Mini 2 I also bought a bit later 
I feel your pain. On my third flight with my first Mini I got involved with some tree branches and could not steer out and down she plonked into a raging torrent 
No chance it could be retrieved.
