At Marham In the 70s we always had a "combat ready" aircraft on 3 hours readiness for Op Dragonfly (later called Tansor). I am pretty sure this aircraft always had a full fuel load (86K in the case of the Victor K1, more for the K2). Would this have meant fatigue issues for these aircraft? It's a serious question as I don't recall it ever being mentioned at the time, although that may just be my faulty memory.
