Green Knight,
thank you for that informative post. I believe that MOD were told about the potential problem and that the addition of FSII would help in this respect. That they chose to not to accept this advice could only be on 'penny pinching' grounds. Before the bulk issue of fuel with FSII we used to carry a 44 gallon drum of the stuff and hand blend it over wing using a Kelson pump !
The bottom line is that the C130 in whatever mark, (Multi Role Capable Aircraft) is the greatest airlifter ever built. Without it we in the UK could not have carried out many of the ops we were sent to do.
