Authors’ Notes:
[1] The responsibility for this debacle remains controversial. In 1945, LtGen Richard K. Sutherland, MacArthur's longtime Chief of Staff, said that days before the attack all B-17s had been ordered to Del Monte, 600 miles from Clark Field, to be safe from Japanese attack. From Del Monte, B-17s could have staged out of Clark Field to bomb Formosa, but Brereton did not obey the order. Only half the B-17s were sent south.

According to Sutherland, holding the bombers at Clark Field that first day was entirely due to Brereton who argued that to know what to bomb he first had to have recon photos of the 25 air fields on Formosa. For his part, Brereton recalled that Sutherland, on behalf of MacArthur, denied him authority to launch any attack. Although the Japanese attacks on Clark, Nichols and other fields reduced the strength of the American Far East Air Force by half, no formal investigation was ever conducted to determine responsibility for the disaster as was done after Pearl Harbor.

Picture credit goes to Gilbert Casse of France.
