Passage: Norway ordered 24 Twin Wasp-powered Hawk 75A-6s, of which 19 were delivered and seven assembled at the time of the German invasion. None of the aircraft were combat-ready. The disassembled aircraft were disabled by a single customs employee who smashed the instruments and cut all the wires he could reach. Thirteen Norwegian Hawks captured by the Germans were part of the first batch of 29 P-36s sent to Finland. Norway also ordered 36 Cyclone-powered Hawk 75A-8s. Most of this batch (a total of 30) were delivered as advanced trainers to "Little Norway" near Toronto, Ontario, Canada, a Norwegian training base established by the London-based government-in-exile. Still later, they were resold to the U.S. and redesignated the P-36G model.

Question: How many employees did it take to disable the aircraft?
a single customs employee
