Old bombs found on Mauna Loa: The rest of the story (Part 1)

An Army Air Corp biplane is prepared for a mission to drop bombs on a lava flow advancing toward Hilo during the Mauna Loa 1935 eruption. Below the plane is one of 20 demolition bombs (center) dropped in an attempt to disrupt and redirect the lava flow, and two of the 20 "pointer bombs" (left and right) that were used for aiming purposes.
