Avtur, as I said, it was a service supply item but was stowage ever considered? I know one piece of kit in a Vulcan was withdrawn because Boscombe Down refused clearance. However, like the Steady Scope, I don't think any thought was given to the CVBS case.
Also compare and contrast a civil airline procedure for stowing flight rations and the ration boxes, cooking utensils, sauces etc in an MPA crew kit.
