Claim
The 11th Air Fleet caught the United States Fifth Air Force on the ground in the Philippines hours after Pearl Harbor
Correction

In December 1941 the U.S. air command in the Philippines was the Far East Air Force, not the Fifth Air Force.

Full reasoning

The U.S. air force in the Philippines at the time of the Japanese attacks was the Far East Air Force. The 5th Air Force history site states: “When war came to the Philippines on Dec. 8, 1941, the Far Eastern Air Force…” and explains that it was redesignated as the 5th Air Force on Feb. 5, 1942. The Air Force Historical Research Agency fact sheet gives the same lineage: Far East Air Force on 28 Oct 1941; 5 Air Force on 5 Feb 1942. So calling the force in the Philippines “the United States Fifth Air Force” for the Pearl Harbor timeframe is anachronistic.

Claim
Following a nuisance raid by Japanese flying boats in May
Correction

The actual Japanese flying-boat raid on Pearl Harbor was in March 1942; the late-May Operation K mission was a canceled reconnaissance attempt.

Full reasoning

This misdates the event. The National WWII Museum explains that the bomb-carrying Japanese flying-boat attack known as Operation K was scheduled for March 4, 1942. It also notes that near the end of May 1942 the Japanese planned another sortie, but that follow-up mission was aborted before it even began after U.S. ships were found at French Frigate Shoals. Naval History and Heritage Command likewise says that on 29 May U.S. ships at French Frigate Shoals prevented the Japanese from refueling flying boats to reconnoiter Pearl Harbor. So the “nuisance raid” was not in May.
