An Army Air Service crew makes the first flight around the periphery of the United States. Taking off from Bolling Field, D.C., in a Martin MB-1 bomber, the crew flies counterclockwise, and since time and speed were not factors, proceeds leisurely across the northern states, down the Pacific coast, eastward along the Mexican border and then arriving back at Bolling. The total distance of roughly 10,000 miles was flown in 114 hours and 45 minutes.
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.
