Officials at NASA's Langley Research Center (LARC) officially opened the Center's new Experimental Test Range (ETR), described as an "electromagnetic wind tunnel." LARC engineers had designed the ETR to determine how low-frequency electromagnetic radiation affects aircraft, to help the military improve stealth technology. The ETR also would assist in testing technologies to enable airline passengers to watch television signals from satellites or to help Internet users make wireless connections. The first military customer that had signed up to use the ETR, the U.S. Army's National Ground Intelligence Center, planned to use models of enemy targets in the test chamber, to see how they appeared on radar screens.
