Employees arrive at the base via a mysterious white bus, which makes stops at Ash Spring, Crystal Springs, and Alamo—where it parks at the courthouse every night.
The white bus is one of two ways that employees get to Area 51 from outside the base. The other way is by JANET flights.
If you want to catch the bus going through Area 51’s gates, be sure to arrive before 8:00 AM.
