(07/08/1999) -- In the cockpit of the orbiter Atlantis, which is in the Orbiter Processing Facility, U.S. Rep. Dave Weldon (right) looks at the newly installed Multifunction Electronic Display Subsystem (MEDS), known as the 'glass cockpit.' At left is Laural Patrick, a systems engineer with MEDS. Weldon is on the House Science Committee and vice chairman of the Space and Aeronautics Subcommittee. He was in Palmdale, Calif., when Atlantis underwent the modification and he wanted to see the final product. The full-color, flat-panel MEDS upgrade improves crew/orbiter interaction with easy-to-read, graphic portrayals of key flight indicators like attitude display and mach speed. The installation makes Atlantis the most modern orbiter in the fleet and equals the systems on current commercial jet airliners and military aircraft. Atlantis is scheduled to fly on mission STS-101 in early December
