Absolutely.
... and I can't help thinking that the 'fear' of a telling off for getting into the situation in the first place, the possibly of damaging an aircraft and the inconvenience of getting back late, override the sensible approach of carrying out a PL.
Therefore pilots will tend to press on and hope it all works out rather than taking an early decision and completing a successful off-airfield PL.
A shame really because in most parts of the UK there is a wealth of suitable landing sites, and therefore options, if the decision to land away is taken early enough.
No aerodrome, airfield or airport is going to turn you away in an emergency. It might prove expensive, be slightly embarrassing and/or inconvenient but at least you'll live to tell the tale.
I know it's been said many times but aeroplanes can be replaced, people can't.
