cannon shells were explosive projectiles; detonating the warhead could destroy the fighter as well. The V-1 was nearly immune to conventional air-combat techniques because of its design, which dispensed with a pilot and piston engine with a cooling system. One hit on the pilot or oxygen system can damage or shoot down a conventional aeroplane but there is no pilot in a cruise missile. The Argus pulse jet of the V-1 could be shot full of holes and still provide sufficient thrust for flight. The only vulnerable point of the engine was the valve array at the front. The only other vulnerable points on the V-1 were the bomb detonators and the line from the fuel tank; three very small targets inside the fuselage. An explosive shell from a fighter's cannon or anti-aircraft gun hitting the warhead was most effective.

The bombs had been seeded with radio-transmitting samples to confirm their range but the results from these samples were ignored in favour of the false witness accounts. Bombs were repeatedly set to fly shorter and shorter distances (and further from the intended targets) as a result of this false information.

Anti-aircraft gunners found that such small, fast-moving targets were difficult to hit. At first, it took an average of 2,500 shells to bring down a V-1. The average altitude of the V-1, between 2,000โ3,000 ft (610โ910 m) was in a narrow band above the optimum engagement height range for
