Fort Shafter in "News From the Front"
On December 22, 1941, the New Yorker reported that on the morning of December 7, Fort Shafter's Information Center had received intelligence that Japanese warplanes heading toward Pearl Harbor. The officer in charge insisted that the planes were B-17 Flying Fortresses coming from the U.S. mainland, and sent no message ahead. Half an hour later, Pearl Harbor was attacked.
