Retired Col. Warren “Bob” Lilly, 74, died Oct. 12 in Alabama. Lilly was a rescue helicopter pilot during the Vietnam War and was shot down in 1965. He spent seven years as a prisoner of war in Hanoi, alongside Sen. John McCain (R-Ariz.). In a statement, McCain wrote: “Bob was not only a good friend, but a real American hero. Throughout the year we spent together as prisoners in Hanoi, I was inspired by his strength and loyal patriotism.”
An Air Force C-17 transport jet recently tested a new technology that could help aviators stay on course even if the satellite-based Global Positioning System (GPS) that much of modern-day aviation relies on is compromised.
