On the evening of 23rd June 1944, Flying Officer Kenneth Collier destroyed a V-1 flying bomb (850kg explosive warhead) by physically ‘tipping’ it with his wingtip.
This was the first instance of a pilot using his aircraft to contact a V-1 and change its course (the first pilot to destroy a V-1 by disrupting the airflow around the wing was Major Richard E. Turner of 356th Fighter Squadron on 18th June 1944).
This method was extremely dangerous and was discouraged by Allied air forces; however, there are several examples of this occurring once pilots ran out of ammunition.
Collier did not survive the war as he was killed in a dogfight on 5th December 1944 over Germany.
