nal Research Council recently released a study concluding that adding “winglets,” those near-vertical wing tip extensions, to most cargo aircraft could save the Air Force millions of dollars in fuel costs, reports Stars and Stripes. The Air Force’s newest airlifter, the C-17 has winglets, but the NRC recommended more research to see if modifying them slightly would enhance fuel savings. It recommended adding winglets to KC-135 and KC-10 tankers and to the C-5 airlifter.
The Air Force has spent more than two years studying cancer risks to Airmen who work with the service's intercontinental ballistic missiles. Now lawmakers in Congress are placing fresh scrutiny on the issue and have prepared legislation that would direct the service to clean silos and launch facilities.
