I have to admit to having read these last posts in some amazement. What was the perceived need to have an escape system on the new Ks after the multiple hours they had flown without, and some 15 years of C Mk1 ops ditto? Is there a history of tankers having to be abandoned after in-flight incidents? Did/do the KC-135s have some such system? I ask in the spirit of genuine enquiry for the absurdity that Beagle mentions seems so obvious to me, yet clearly did not to a number of folk who must have been involved in the specification.
