It's became very difficult to keep track of strategic bomber flights after Russia announced the resumption of regular patrols (without nuclear weapons on board, I should underscore again). I guess we'll just have to assume that at any given day some bombers are indeed on patrol (although it does not look like they will maintain a 24-hour presence in the sky). According to one report, the Air Force considers it normal for a bomber to conduct about two (long-range) flights a week. I hope they will take Saturdays and Sundays off.
