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.
Dozens of fighter jets gathered at Tyndall Air Force Base in Florida last week to kick off one of the service’s biggest air combat exercises despite the government shutdown. More than 50 aircraft and 500 personnel are participating in Checkered Flag 26-1.
