The investigation into the June 22 crash of a Predator unmanned aerial vehicle flying a training mission at Creech AFB, Nev., indicated that the UAV suffered rapid loss of engine oil because of a loose oil filter. A statement from Air Combat Command said the accident board believes a technician improperly aligned the oil filter, but it also noted that the design of the filter itself contributed to the accident.
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.
