dragartist,
ah the fuselage bending moments saga. Better not go there. As regards the vertical C of G of the heavy drop platforms we at the coal face were in blissful ignorance of how marginal these limits were. I only found out from you contributions to this thread ! Mind you I confess to asking the JATE designers how they calculated the vertical C of G of the loads especially the war load 'piggy' backs some of which looked very 'iffy'. I was effectively told that if the load was approved for dropping then ALL variations had been taken into account. Umm !
The Beverley had a vertical C of G load plot on the trim sheet but the Herc did not.
