Coff,
you have to remember that the disconnects on the parachutes etc were all pneumatic and clockwork , to introduce anything explosive would have caused alarm amongst the powers that be . Couldn't possibly allow the loadmaster to have control of something that went bnag! many a happy time spent following through on the ads handle as a backup fpr the co forgetting to press the chute release button. Also pulling the EPERU handle and being left with a hanful of handle and frayed wire (it had operated correctly though) just broke afetr doing its job.
