I was assigned to their B-70 project in the hydraulic power section. At the time all contractors were required to minimize heat production of their systems. The skin heat created by Mach 3 cruise was a real problem. Piston driven pumps were out because of the heat generated so new "swash-plate" technology had to be designed. Hydraulic lines hade to be routed thru the fuel tanks to cool the fluid down to acceptable levels. This worked ok if the tanks were fairly full. Rubber O-rings were "out" because of the heat so a stainless steel subtitute that cost about $1000 apiece had to be used. I left Vickers for Pensacola in October 1960. So ended my early experience with B-70 design problems.
