Early on the morning of June 4, some 22 PBYs took off for searches from Midway. Does anyone know what area they covered? This would also determine how wide the individual search sectors were. Admiral Fletcher launched a search to the north from Yorktown, so apparently he was not sure the area NW-NE of his task forces was being covered. I would guess the PBYs probably did not search much east of 000 degrees, due north from Midway island. I could see them searching the entire western semi-circle, down to 180 degrees, but would they go any further east?
