I take your point about not wishing to black the main runway at one of her maj's airfields, but our North airfield is quite small and on good weekends practically always has gliders on it! We also have a grass strip and my instructor has indeed suggested when practising glide circuits that it may be better sometimes to go for the grass strip in a real emergency.
Fair point. Frankly if my capacity was maxed out with an emergency (as it probably would be as well as some uncomfortable squelching in my pants) I'd black any runway in the country if it meant my passengers and I lived, runways can be replaced and my face is more important
