Tipping V-1s was done because the fighter drivers had run out of ammo. It was not a preferred tactic by any means, but a tactic of last resort

The tipping photos show up now and then, although I believe the first one is someone playing with a photo. I think they tried to draw a Spit shape without much success

The last two are the ones that show up in books now and then and are clearly a Spit XIV
The rocket shot is from a Tiffie. Actually lots of those shots around. I got some from a Spit XII driver who ended up in Tiffies in 45.
Decent batch of photos though.
