, formed the outer skin of the aircraft. The metal lattice gave the structure tremendous strength, because any one of the stringers could support some of the weight from even the opposite side of the aircraft. Blowing out one side's beams would still leave the aircraft as a whole intact; as a result, Wellingtons with huge areas of framework missing continued to return home when other types would not have survived; the dramatic effect was enhanced by the doped fabric skin burning off, leaving the naked frames exposed (see photo).

In one case as a result of a fire in the wing caused by battle damage a Wellington co-pilot was forced to climb out of the aircraft while in flight kicking holes in the doped fabric for foot and hand holds and physically smother the burning upper wing covering.
