Hidden in there is Belgian Squadron Leader Boussa's 50th Kill for Acklington - a happy accident - not for the Germans though!

Quite astonishing the rate of fire of those 20mm cannons, he got 82 rounds off in 6 seconds, and that's with one gun jamming part way through the process.
Also 595 rounds of .303 in 7 seconds, which he was just using to establish deflection for his cannons.
Killing Machines.
