what about all the testing that goes on In the Mohave desert....
Edwards AFB? Many large planes are seen at night with
black paint jobs and white dots (simulate stars I guess)
aurora seen there
The white dots are sensors, for the test planes to collect flight data....
As for under Area 51, you're likely to find...
1. underground R&D labs and hangars...with lifts to surface hanger bays.
2. underground tunnels connecting to Los Alamos, White Sands, and other areas of the complex, such as S-4.
3. In S-4, is where you'll find the "live on base" personell, and R&D labs, and concealed hangars, housing recovered alien tech (biologics are at
other locations...not near here)
4. security and defense system
5. bunker-like areas
6. toxic storage facilities
