How many "local/local" flyers would cope without a chart if their home airfield was suddenly closed?
Depends what your "home airfield" is ... given that mine is Cambridge I do rather feel that I could find any of Bourn, Duxford or Stansted without anything other than looking out of the window and following roads. I appreciate that there are parts of the world where it isn't quite that easy.
(And if anyone is reading this who really doesn't know the answer ... bottom line, scream for help on 121.5 and they will point you at a runway.)
