The experimental-and by this time militarily obsolete-Douglas XB-19 bomber is flown for the first time by Army Air Forces Lt. Col. Stanley Umstead and Maj. Howard G. Bunker (with a crew of five) at Clover Field, Santa Monica, Calif. The XB-19, with a wingspan of 212 feet, a length of 132 feet, and a height of 42 feet is the largest aircraft built until the B-36 six years later.
The KC-Z4, a blended wing body tanker concept being developed by startup JetZero, could fuel larger groups of aircraft at longer range to hold more targets at risk, company officials say.
