Vol. 2 No. 38 ……. The aviation engineers’ biggest project – construction of a labyrinth of paved runways to handle history’s greatest concentration of military aircraft has just begun in the Ryukyus. (Story Page 3). BRIEF’S cover this week shows engineers blasting coral on Ie Shima. On Okinawa alone, the smallest of the airstrips will handle twice as much traffic as LaGuardia Airport. Before their job is done, the engineers will have moved enough coral and earth to build a mountain one mile high, 2000 feet at the base. Photo by Sgt Fred Shelton.
