(04/29/1999) --- STS-101 Commander James Halsell (left) and STS-98 Commander Ken Cockrell (right) look over the recently installed Multifunction Electronic Display Subsystem (MEDS) in the cockpit of the orbiter Atlantis, which each will command on their upcoming respective missions. The new full-color, flat panel MEDS 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. . The first flight of the upgraded Atlantis is STS-101, scheduled for launch in December 1999; the second flight, STS-98, is scheduled for launch in April 2000
