I use to live on Pye Bank and I'd see helicopters land there occasionally during the 80s and 90s.
Me and my pals would ride our bikes around the helipad and up towards the sky village. Once we saw two helicopters had landed there, we approached them to have a look inside out of curiosity. Two blokes jumped out of them and chased us away. Great times!
I'll be back up there on the 7th on the playing fields as my U14's football team are playing away there. The home team manage we're playing against is one of my pals who was with me when encountered the two helicopters back in the day. Should bring back a few memories.
