During the “Incident contacts” I mentioned earlier ..We did acquired a new target – The American SR71 Blackbird A special kind of reconnaissance aircraft. They started their run from England And followed the same pattern in the Baltic sea, every time they made their way there. They approached on civilian air-craft route, so we always knew when they were coming We had worked out a special kind of attack pattern, just to get this one (The SR71) Command asked me if I had enough fuel for an high altitude contact If one confirmed, one was routed to the Southern tip of Öland Climbed to 8000 meters When one turned north again, the SR-71 had gone passed Gotland more or less. Continued climb – Turned on the afterburner and went super-sonic Continued climb in at least Mach 1,2 Straight for it It (SR-71) operated on varied altitude, but at least 22 000 meters, in Mach 2,2 Sometimes faster If it was a clear day, one could see them up there, in the blue skies And we successfully acquired Air-to-Air lock on them, all the time up there. (Robot 71=British Sky-flash) Of course with fictitious missiles We never fired live ammunition One could see it very well up there – at altitudes above 16,000 meters, the sky isn’t blue, it’s purple or black One could always spot the SR71 – They left a clear visible trail From their special kinds of engines, called ram-engines. Which are just like huge after-burners It’s a must in those altitudes. Our engines demanded super-sonic speeds too, to even function in those altitudes I’ve accomplished engagements like these on many occasions They (US-airforce) always used the same pattern – Except for one time When they experienced electrical failure And they were forced to descend over Gotland They didn’t want to steer towards the Soviet Union So they turned towards Sweden They managed to get down to lower altitude and it’s the only time they ever violated Swedish air space But it was due to an emergency, so it’s quite alright.
