Flying a Nieuport 28, Army 1st Lt. Edward V. Rickenbacker, who would go on to be the leading American ace of World War I, records his first solo victory, downing a German Pfalz. Flying with the 94th Aero Squadron, he had recorded a half victory, his first, on April 29.
Members of the House Armed Services Committee say the AIM-260 Joint Advanced Tactical Missile program has been set back three months due to the ongoing government shutdown. The comment is noteworthy because the JATM's status has been kept tightly under wraps.
