Several of the guns had to be "disabled" as the German builders were so proud of their "fast plane" tracking capability that they neglected to put a "manual" button on the set up.
For the Brit pilots - fully expecting in the finest Bushido tradition to "not be coming back" - they must have pissed their pants with laughter as they floated above the ship at 10 mph and the cursing Germans were unable to hurl anything heavier than insults.
Even the 300000 ton Pom Pom mount had a manual feature. Tho it would conceivably take 9000 men to turn it! The quad .303 mount was a similar bastard and one laughs imagining 15 year old boy first class Nigel attempting to swing the mount on his own. But hey - give the Brits their credit - it could track as fast as you could turn it. Or as slow as needed. Which is an option/luxury that Lutjens didn't have.
An epic example of over-engineering. Apparently folk don't learn as Korean War Sea Furies and Vietnam War Spads would knock mach-speed MIGs out of the air.
