The explosive was attached to a rental car that a customer drove away Monday at Ted Stevens Anchorage International Airport.
Airport Police and Fire Chief Jesse Davis tells KTUU (http://bit.ly/1reBCYc ) the explosive was recovered Monday afternoon in the Anchorage area.
He says the amount of explosives in the vehicle was small and didn't pose a threat to the driver or the public.
The department is reviewing policies to make sure officers don't lose track of explosives again.
