Its not only the aircrew that suffered from "spillage"; the underfloor areas at the back of the C130 suffered quite a lot of skin corrosion and the "Pork chop" fittings on the lower longeron to the tail risked stress corrosion. The amounts of fluid apparently were shocking. Hence there was a mod program to introduce the larger pot (for burly paratroopers with poor aim....). I got introduced to the mysteries of the services supply system while a mere sprog at the RAE to do this on the Met Flight Herc (XV208). Only a couple of years later, as a test engineer at the Design Authority, testing a cracked fitting was one of my first jobs. But when I had to do some in-flight measurements on the XV208 after servicing, then it was ideal opportunity to complete the job and flight test the newly installed facilty !
