[kurlannaiskos]

although rarely used by the American Air Forces the Boston could be used with two gunners.
one in the upper rear 'clamshell' position and the other in the lower aft fuselage, this poor soul had to lay prone.
hence, 'a three-seat bomber' but able to have four men in the crew.
(the Soviets sometimes used this position)


(L) equals Light
(H) equals heavy
both are in-accurate as these are Medium bombers.
