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 United States Air Force is flying less than historic norms and funding for acquisition and readiness is on a path to further hollow out this too small and old force to that is incapable of sustaining an enduring combat air campaign.
