I was involved with the A&AEE trials of a JATE designed ASRA for the Herc tanker. The tankers were an obvious choice for a Search and Rescue aircraft in the Falklands and so JATE designed and built a platform that could be positioned in the port para door to despatch three linked MS10 containers. The trials were on the whole a success, but we never issued recommendations for a CA Release for the ASRA as it was pointed out that having three smoke floats secured to the cabin wall within feet of a single skinned fuel tank was probably not all that sensible. Also, as the aircraft itself didn't have a CA Release as result of the tanker mod we couldn't issue recommendations for the ASRA.
Incidentally every time we despatched the three life rafts two out of the three inflated inverted, I never complained about dinghy righting drills after that.
