To have been effective Bristol would have needed to work on the Centaurus powered licence built Constellation from 1943. Kelly Johnson gave a talk to British designers at either the SBAC or RAeS in London around 1943 about the benefits of higher wing loadings and thinner aerofoil sections (combined with powerful flaps) (as in the Constellation) but was ignored by the designers of the 'Brabazon' which had a ridiculously over-large wing.
What were the structural advances made in the 'Brabazon'?...I understood that the infrequently-flown prototype suffered from structural cracking which should have been deeply worrying but possibly a valuable lesson in what not to do.
