Summary
It has finally seeped through the rock like substance surrounding the withered husk of my brain that there's something wrong with the PB-1B "Nancy". It's too aft loaded to be safe to fly. With a normal aircraft, the Center of Gravity (CG) is forward of the wing's Center of Lift (CG), so that when the wing stalls (loses lift), the nose of the aircraft pitches down, aiding recovery from the stall. Pitching the nose down reduces the angle of attack (the direction of airflow meeting the wing) & diving increases the airspeed over the wing, both contribute to recovery from the stall. This is a gross over simplification, but covers the basic idea. When the wing stalls, with the CG behind the CL the nose pitches up, deepening the stall. The aircraft then falls out of the sky. At the altitudes the cats are limited to, the stalls will usually be fatal. To fix this the wing & engine need to be moved aft & the observer relocated under the wing. This should move the CG forward enough to fix the situation before more crews are lost.
