Getting off-topic here, but after a bit of Goooogling I find that the Fort's maximum bomb load was 12,800lb, rather more than the Mossie could carry, methinks. BUT... its fully loaded max range was 1,100 miles. Berlin is 600 miles or so from the East Anglian bases, which is surely at (or beyond) the limit of its range for a round trip? Obviously with a slightly less-than-maximum load, it would get there back and still outdo the Mosquito. At the Fort's normal load (6,000lb), the Mossie would beat it on speed. So that's it, I guess. Another mostly-believed story not based on the full possibilities... back to the topic?
