Airmen of the 87th Aerial Port Squadron use chains to restrain a 463L pallet (a standardized pallet used for transporting military air cargo). This challenge simulated tying down a vehicle on a C-17 Globemaster III and calculated the effectiveness angle of the chains. A forklift was backed up to the edge of the pallet, and the group was given two different angles and lengths to figure out the effective restraint that each chain would provide.
