In '89 I had just departed my pal's airstrip at Langham and was aiming for Old Sarum via scumbling round various zones [In my CFM Shadow 3 axis micro] when I glanced up and did not see the underside of a high aspect ratio black machine lowering its way to Sculthorpe. Later that same year I was approaching and cleared overhead Marham at 4000 feet enroute Pocklington when I didn't see yet another high aspect ratio device that had lifted off and was pointing at our two machine loose group [Shadow, Streak] so I advised Marham that I had this device visual and it was getting ever bigger and still aiming at us! Marham told me he was doing circuits at 2000 feet and at that moment he levelled off and my blood pressure approached normality.
Then at night near Leiston Suffolk [Bentwaters nearby] seeing the cluster of lights and with the moon behind not seeing another type of pointy weather balloon wheels down on approach was great fun.
