QUANTICO, VA - FEBRUARY 27: Exhibit artist Shawn Hensley uses a rapid-drying alge-based molding material to make a cast of United States Marine Corps Captain Bill Heiken's hands during a casting session at the Quantico Marine Corps Base February 27, 2009 in Quantico, Virginia. Active duty Marines, including Heiken, a helicopter pilot, assumed poses portraying WWI-era Marines while being modeled for life-size cast figures. Heiken's body was cast to look like that of 1st Lt. Bernard L. Smith, a pioneer in the early years of Marine Corps Aviation, as he flew a Curtiss A2 plane in January 1913. The cast figures will be installed in exhibits at the National Museum of the Marine Corps's new World War I gallery scheduled to open in the spring of 2010.
