Retired Lt. Col. Robert L. Riedenauer, who flew development aircraft such as the SR-71 and U-2 while in the Air Force and later, as a Lockheed Martin test pilot, the F-117 stealth fighter, died at age 70 on April 23 at his home in Palmdale, Calif. The Associated Press reports he had fought a long battle with cancer. The City of Lancaster, Calif., inducted Riedenauer into its Aerospace Walk of Fame in 2002.
The Air Force has approved Airmen to start training with the EA-37B Compass Call Mission Crew Simulator, BAE Systems announced. The system will provide realistic training and mission rehearsal for EA-37B crews, who perform long-range electromagnetic warfare missions.
