Which is correct, but the B-17 didn't either, it's range was quite restricted with an 8,000lb load.
Interestingly, the RAF used stripped B-24's in the BMI theater, and carried a 12,000lb load some 1,400 miles in one case. Note of course that the return fuel numbers are also much smaller, since you're short all those bombs, making your fuel numbers much less. And operational ranges are two-way typically. -Adam Bob Blakely wrote: > Yes, but I assume they didn't take that load all the way to Berlin and that > they were stripped of nearly everything not absolutely necessary for flight. > > Payload vs fuel is the most common trade off made.
