Portal:Civil Aeronautics Board, Aviation Accident Report: Eastern Air Lines Flight 5 (1942)
“ Captain Cann’s action in descending to the 2000-foot level over the Charleston range station to "take a look" at the airport cannot be criticized in the light of the circumstances existing at the time. Upon approaching Charleston he heard part of the 1:30 a.m. sequence weather broadcast by the Charleston range station, which indicated that Charleston then had 1/2 mile visibility. The captain testified that due to the thickness of the fog he could not see the lights of the airport and therefore concluded that it would be unsafe to attempt a landing. ”
