Willard, I think he meant 40 plus as in over forty years old, same for twenty plus.
Nobody's bitten yet about Lossie and the LFAs or Garvie Island in the event of Scottish Independence? A couple of years ago that would have been Lossie, Kinloss & Leuchars, but we know who closed the latter two RAF stations. I say RAF as there is still a military capability, just not light blue. not even bright yellow helicopters, as even that capability's been privatised!
