HILL AIR FORCE BASE, Utah -

All six crew members aboard a C-130 air tanker escaped injury when the aircraft on its way to refuel for a firefighting mission was forced to make an emergency landing at Hill Air Force Base near Ogden, Utah.

Air Force officials say the aircraft owned by the Wyoming Air National Guard experienced an inflight emergency around 1 p.m. Sunday. It belongs to the Guard's 153rd Air Refueling Wing.

The air tanker is one of two Wyoming Gov. Matt Mead recently activated to help fight fires in Washington, Oregon, Idaho, Utah and California.

Hill Air Force Base said in a statement Sunday that the aircraft had planned to refuel and resupply at the base. It said an investigation is pending and more information will be released when it becomes available.
