They were piloted by Kenneth Taylor (the aircraft with the tactical number "316"), and George Welch ("160"). At that time 47th PS was practicing gunnery at Haleiwa, a secluded field on the North East corner of Oahu Island. This area was not attacked by the Japanese (Pearl Harbour lies on the opposite side of the Island). The runway ran along the sea coast. This is how the fighters could have appeared, shortly after take off. The background, obtained from www.hawaii.gov , shows an authentic part of the shore near Haleiwa.
