Thanks for the links, pagen01, as the word “airbase”, without any further elucidation whatsoever as to which airbase, or what meaning of the term was intended, meant nothing to those outside your narrow geographical area.

And no, I hadn’t read the 3-page thread started weeks ago about it, as it looked (from the preview blurb that pops up from the title in the index page) like just another thread about a WW2 base.
