Joking aside, what exactly do these people hope to accomplish here?
Lets say some, or even all of them manage to get to the base, then what? Anything of alien origin is going to be buried deep within the facility, likely underground, and between countless security checkpoints and blast doors.
I hardly doubt the Area 51 guards are going to suddenly grant unrestricted access, so these people are going to arrive, get into the base, and then, practically, hit a brick wall, cause they're never going to get to the good stuff.
It's almost like a half baked plan without any logical thought behind it.
