hmm.. I'm not sure what present situation is (I'd be interested to hear), but:
after 9/11 in US, when the absolute restriction on GA VFR leisure flying was lifted, in the Washington area the routes between White House, Andrews AFB and Camp David could be NOTAM-activated as Restricted at no notice whatsoever
, with no way for the GA pilot flying VFR to discover this after takeoff. Violation would probably lead to intercept by F16 or armed helicopter, and (for survivors
) likely severe FAA and Federal criminal sanctions. As a result, local GA pilots had to treat these routes as Permanently Restricted.
I'm guessing that non-radio, non-transponder flying in that area is much rarer than in UK, and it may be that there is now an effective way (eg FIS) to notify airborne pilots in the relevant vicinity by ground-air data transmission.
