What is also worth noting, and often forgotten about the "Land clear rule" is that you cannot use playing fields, golf courses and the like as your nominated landing area if it does all go quiet.
As this CAA safety sense poster states :-
GA Safety Poster: Crossing Large Built Up Areas | Publications | CAA
There are some circumstances where you really would have no choice, on approach/climb out of plenty of airfields for example, a park or playing field would be your only option if a return to the airfield was not possible.
