Getting all that lead in the air was quite a problem. While in theory the planes could stay airborne for days things like pilot fatigue, food and stresses on the aircraft meant it wasn’t feasible at all![]()
From what I've heard was that whenever the nuke B36 flew , it was accompanied by another aircraft containing decontamination troops.
In case the nuke B36 went down - those poor blokes had to cordon the area off and try to decon the crash site.
