Indeed they do.
I was the FO on the Be20 for a year and a half.
The Airfield is controlled by Capt. Peter A M Spofforth (nice guy), and if you call during office hours you will probably get through to either Brenda or Stella - both of whom will deal with any questions you may have.
The gliding club ususally ops most weekends and evenings in the summer. Head guy is Peter Lewis. Brenda / Stella will be able to give you his contact details.
The airfield is unlicenced at present, so no flight instruction.
If you happen to pass in - say hi from Steve.
