Rumbo, good point made. Exactly why I did not post any direct suggestions but rather areas where RAIM could look for himself.
If there is no threat, perceived or otherwise (how do you know if there is an unperceived threat?
) then that would suggest no security measures need to be taken.
Failing that, you could surround the aircraft with three rolls of razorwire and an infantry company each night...
With those tongue-in-cheek comments I shall close this thread.
