What Princess Kate’s Grandpa Did in WWII

Gave the heave-ho to V1 rockets as a “doodlebug nudger”.
Via suburban banshee, who adds,

I’d never heard of this, but of course my dad had. What they did was fly up to the V1, flip it up and over by nudging the V1′s wings with their wingtip, and thus screw up the V1′s gyroscopic guidance. The doodlebug nudger would fly away, and the V1 would fly right into the ground.
