fascinating stuff - planespotting led to discovery of cia torture flights

"What becomes interesting is anything which is�what do they say in geometry? Acute. Any kind of acute angle between arrival and departure becomes interesting to us because it suggests that the stop was a destination. A place you wanted to go." Sifton draws a line from the Middle East to Germany to Poland, an acute angle: "We were especially interested in airports that were not large, public airports.... Frankfurt is not even close to being a suitable candidate for an extremely sensitive clandestine CIA detention operation. By contrast, a small rural airport which isn't even open for regular civilian transport such as Szymany airport [in Poland] becomes suspicious, especially because it appears to be a destination."
