Interesting.

I was on the receiving end of these beasties. We called them
"doodlebugs" The noise they made was a bit like a 2 stroke motor-bike.

They were supposed to dive on their "targets", but the pitch change
starved the engine which cut. If you heard one do this you had about 30
seconds to get under the kitchen table.

British Scientific Intelligence conned the Germans into reducing the
range of the V-1s aimed at London, which were undershooting anyway.

There is a belief around that RAF pilots could sometimes upset the V-1's
by using the Spitfire's wing-tip vortices to tip them up. Looks like a
tall story to me.
