I read a report from a mig 31 jockey who intercepted an sr71 over soviet airspace ,nothing is impossible stealth technology does not make you totaly invisible just harder to see and according to an RAF pilot friend of mine the older longer wave misile systems dont have too much problem seeing you , the newer shortwave radar setups are the ones that have the problem.
Back in the late 60's Lockheed were well upset when the brits tracked the blackbird for it's first showing in the paris (or was that farnborough forgive me im well tanked up in Prague on me hols
) airshow , they were actually tracking the heated air around the blackbird , but traking it none the less.
While were on the subject of shooting down U2'S didnt Gary Powers loose a fair bit of hieght enabling the missiles to get him ??????
Anyway just my tuppence worth..
ta ta pip pip an all that : back to the bar ....dobrey dan:)
