Would someone be so kind as to give me the upper airway frequency for aircraft on UA2? or UB3? (not even sure it's one of those, UA1/B4 maybe?!):o travelling southbound over BPK, or in the vicinity of that? Thanks.
Secondly, a bit of guestimation here I suppose, but if I can see a high-flyer trailing on the horizon, roughly how far away would it be? 60 miles? More?
Cheers!
