Just curiosity, but in case of a real life-threatening emergency (where you can't fly to closest airport or strip), would they (Air Force, military or whoever) allow the plane to land on the Area 51 airstrip? Have there been any occurrences that we know of?
R-4808, the restricted area around Groom Lake, NV, is restricted at all altitudes. It is also surrounded on multiple sides by other restricted spaces and MOAs.
No routes, low-altitude or high-altitude, go through the area. No one has any business being near there to begin with, so no one will have any emergencies in the area.
Assuming a hypothetical situation where you have lost all controls and engines and your driftdown will bring you smack in the middle of Area 51.
I would imagine you would be very soon flying next to America's finest and if you are something like a Cessna 152 they would probably allow you to land.
Your chances of leaving ... now thats another story!
