Sgt. Dave Gray, a crew chief with the Maine Army National Guards 3rd Battalion, 142nd Aviation Regiment, watches carefully to ensure that the 4,000 pound cement block he just attached for transport goes up smoothly and without disruption to the UH-60 Blackhawks flight patterns. The flight crew ensures that the helicopter has the power to lift the load, and the crew chiefs test the cargo hook to certify it is airworthy before the object can be lifted.
