US Air Force B-2 bombers flying from Andersen AFB, Guam, are dropping weapons on Australia’s Delamere bombing range this week as part of a bi-national exercise worked out last year. (News of the plan last year sparked a local outcry, as critics claimed that past training activity by Americans had spawned accidents.) The Christian Science Monitor reports that this marks the first time US aircraft have used the Australian range since the two countries signed a bilateral agreement in 2004.
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.
