More than 40 Air Force personnel from Hill Air Force Base in Ogden worked Saturday to recover three solid propellant missile boosters spilled in a truck crash on Thursday.

The Office of Public Affairs at HAFB said the recovery teams planned to leave Saturday evening for the return trip to Ogden.A Minuteman III missile transporter crashed on I-15 Thursday morning about 25 miles north of Idaho Falls. The missile components were en route from Malmstrom Air Force Base near Great Falls, Mont., to Hill.

The interstate, the main north-south route in eastern Idaho, was closed for a time Friday while crews worked to separate the three boosters and prepare them for transport.

The interstate also was closed for two hours Saturday for the same purpose. The Idaho State Police dispatcher said traffic was detoured onto Idaho State Road 21 west to Howe, then northeast on Idaho State Road 22 to the freeway at Dubois. Officials said that would add about an hour to travel through the area.

The driver of the vehicle, Barry Hatch, was treated and released from a local hospital for a broken arm and minor injuries. Hatch is an employee of Uintah Freightways Co., which transports the boosters under contract.
