The largest coordinated strafer attack of the pacific air war to date was carried out on January 7, 1945. B-25 aircraft from the 345th Group and A-20s from the 312th and 417th Groups sent 132 planes over Clark Field to strafe and drop parafrags on the dispersed Japanese aircraft. This spectacular photo was taken from a 312th A-20 and shows the many aircraft of the first wave stringing their parafrags over the targets below. A 345th B-25 is at right center flying above the remnants of Japanese aircraft.
