My replacement pilot in Bao Loc was Captain Roger Sawyer. He came back to Bao Loc and found he was above the clouds. He could not see Bao Loc or the airfield. His remedy was to call the MACV compound, telling them about the situation, and to shoot up a flare. He could then see the flare. That would tell him where the MACV was located. Knowing that the airfield was South of the MACV, he knew that there were NO mountains in that direction. He saw the flare and flew South, letting down through the clouds in IFR conditions. The men on the ground told him that there was a ceiling of clouds of approximately 2000 feet above the ground. After breaking out with visual flight conditions, he flew to the airfield and landed. He had to be a great pilot to be able to solve the situation and land.
