Now we have people saying the planes were faster than reported!
Sorry guys, they weren't faster. A Mosquito quoted at 408 mph went that fast ± a few mph, not 424 mph. Just like all the other WWII aircraft met their factory specs. Production aircraft varied a few mph, but not by many.
WWII aircraft weregenerally as good as their specifications when relatively new and clean. As they aged or got dirty, they got worse than specification, not better.
Still happens today.
According o the pilots that flew them, Mosquito B Mk XVIs with the 4000 lbs cookie bombload were able to do a maximum of 408 mph with a full bombload, but 416 mph with bombs gone and half load of fuel.
B Mk XVI speeds also varied due to the different engines fitted, Merlin 72/73 in the first 80, Merlin 77/76 in subsequent deliveries.
