Prior to 617 GS arriving from Hendon in the late '60s, 613 GS from Halton operated detachments there at various times, mostly (but not always) when Halton was waterlogged in winter. I did the very first launch there on the first detachment in a Mk 3 with Mike Duncombe (he'd been aerotowed in from Halton) and I also got the first Air Cadet Soaring Certificate there about a year later.
