This was subsequently confirmed and he was made up to Flying Officer in May 1942. Promotion to the rank of Flight Lieutenant followed in 1944.
He was part of a scheme to booby trap captured fuses and smuggle them into German ammunition stores so that bombs would exploded when being dropped, so destroying the enemy aircraft.
The Germans discovered the scheme but were forced to destroy large numbers of fuses as a precaution. Harrison had retired with the rank of Wing Commander in 1949, but remained in civilian appointments with the Air Ministry until 1970.
