A Japanese attempt to reinforce Lae, New Guinea, is foiled by aircraft of the Southwest Pacific Air Forces during the Battle of the Bismarck Sea. Modified B-25s are used for the first time in low- level skip bombing techniques. More than 60 enemy aircraft are destroyed, and some 40,000 tons of Japanese shipping are sunk.
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.
