Yes I saw a RQ-4A Reaper up over USA (I'll have to look back at exactly where) and yet another US RQ-4A Reaper that patrolled from Greece North all the way to the Baltic sea, seemingly searching around Lithuania at FL510.  And yesterday a U2 just North of San Fran doing a 100nm legged triangle search up at FL310. That day, 17th Nov, I have never seen so many aircraft flying but not just in the USA but Europe was full of Military flights!
