Not familiar with what's actually at Woodvale, Topcliffe or Syerston
Topcliffe is occupied by the Army as Alanbrooke Barracks, and home to an RA Regt, and that's been the case for nearly thirty years. The runways have been used as a satellite for Leeming (RN EFTS), Linton, and by VGS. I can't see there being any money to save by ceasing to use them.
