I was looking at a chart the other day, and my eye was drawn to cluster of airfields running north to south down the A1, Leeming, Topcliffe, Dishforth, Linton-on-Ouse and Church Fenton.
Given the current, and projected, size of UK military avaiation I'm afraid the thought that immediately sprang into my mind was:
"...that set up is totally unsustainable...".
