Retired Col. Donald J.M. Blakeslee, one of the top scoring aces of World War II, died Sept. 3 at age 90 in Miami, Fla., per a notice in the Sun Sentinel. According to the official Air Force record, Blakeslee scored 11.5 victory credits as a member of the Army Air Forces. However, various accounts note that he flew first with the Royal Canadian Air Force, making three kills by 1942 when he transferred to an American Eagle Squadron with the Royal Air Force and shot down two more enemy aircraft before the AAF incorporated his unit in September 1942. He flew Spitfires, P-47, and P-51 fighters. He took command of the 4th Fighter Group in January 1944.
The Space Force is playing midwife to a new ecosystem of commercial satellite constellations providing alternatives to the service’s own Global Positioning Service from much closer to the Earth, making their signals more accurate and harder to jam.
