I was working, and although not microlights (which, as AlanM says, hardly show in radar) I was treated to two streams of gliders stretching from just outside of Lyneham to the Malverns and the other from the same point up to the East side of Gloucester. 30 or 40 in each stream, the streams stretching 20 miles from front to back.
Avoiding action - fat chance! All you can do is call it out and hope for the best
