Firefighters at Eglin AFB, Fla., have been testing a new chemical protective suit that would be worn as an undergarment not an overgarment, as is the case now. The new kit would be lighter and more flexible and features a mesh-like design that makes it cooler, said officials. The 16 firefighters in the test went through standard firefighting exercises, including dragging heavy hoses, a 150-pound “victim,” and consecutive trips up and down a ladder.
Denys Overholser, the Lockheed Martin engineer whose insights on the mathematics of radar cross section led directly to the first operational stealth attack airplane and permanently reshaped combat aircraft design and tactics, died April 28 at the age of 86.
