Wolk (2010) states that a B-29 at high altitude could carry only 35% of the load of a B-29 at modest altitude. In a curious role reversal, a small number of B-29s were fitted out as navigation escorts for P-51 Mustangs making the long flight to Japan. These aircraft carried homing beacons to allow the Mustangs to home on them for the return flight.

Many qualities of the B-17 have been built into the B-29. The B-17 tail was one step in the development. In the early experimental stages, a B-17 was flown with dual turbos, the B-29 fin and rudder, the B-29 stabilizer and elevator, and even with the B-29 ailerons. The B-29 is the first of the "very heavv bombers."

B-29. The most widely produced Superfortress model was the B-29, of which 2,537 aircraft were built. The B-29 featured the first ever fully pressurized nose and cockpit in a bomber; an aft area for the crew was also pressurized. Since the bomb bays were not pressurized, a pressurized tunnel was devised to connect the fore and aft crew areas.
