It happened again on Thursday. Aircraft approaching Malvern hill from the West at around 100ft. Skirts North of the town then heads up the East side of Clee Hill and accelerates away from me out of sight. Definitely a helicopter and at or around 100ft. I was chasing it at 95kts. Time was dusk.
How fast would one of those go?

ps waiting for a knock on the door from SB now. I've been browsing for info on Menwith Hill lately as well... oops.
