We got lost in our motor home north of Calico, Nevada, about midnight. We wandered about for a couple of hours then shut down for the night about 2 am. After we had watched the stars for a half hour we noticed we were near(4 miles +-) an active airbase. Suddenly a group of very fast lights dropped over the base and began to zip around the airbase. Suddenly a large yellow globe descended and hovered over the airbase. A small globe came out of the large globe (it kept hovering) and descended to what appeared to be the main base. The other lights kept zipping about the airbase and the large globe kept hovering. After about 30 mins the small globe ascended up to the large glove and disappeared inside. They shot off into the firmament. Followed by the other skipping lights. It all appeared routine and after they left things continued on as before. We do not know where we were, somewhere in northern Nevada and in the morning we found our way back to the hyway and proceeded to Vegas.
