The Aerospace Research Laboratories, like the Rockwell Science Center, are located on top of a hill. Down below the hill are several of the Air Force development laboratories. Just as Mr. Caustin comes up to the Science Center, people come up from the development laboratories and keep us very much in touch with the real world. We occasionally go down and talk to them, too. The interaction between the two places leads to some interesting things. In fact, I'd like to talk to you about one such interaction today.
