If you have no tried goggle earth.com your missing out. I have just found area 51 and you can zoom down and see planes and cars! Area 51 is difficult to find but you can see all of it. You can even pan down in a 3D format!!
p.s. you will need a very high end PC to use google earth.com. It's memory hungry!!
