Twice a year an active ICBM is picked at random from the mid-west, the nuclear warhead is removed, and the rocket is taken to VAFB where it is launched at Kwaj.

Twice a year an active ICBM is picked at random from the mid-west, the nuclear warhead is removed, and the rocket is taken to VAFB where it is launched at Kwaj. The entire purpose of this very common event is to make sure that ICBM's work as expected. I live in the area and am woken up by these tests. If you live on the West Coast, you can see them. You can also Youtube them (VAFB missle test).
