Our ops manual was updated to cover flying with increased CB activity during the summer. Guidlines were introduced, for example min 2000FT verticle clearance, 20nm horizontal on wx radar, 10nm visual and in a TMA 10nm via wx radar and 5nm visual (I believe).
I have seen some BIG ones over Eastern Europe this summer, not when compared to the Asian/USA monsters, but easily FL400. Its amazing how close to these bad boys some people got.
I like to keep my distance from them to say the least
