The author took the risk of flying through the black clouds. He couldn’t see anything. The aeroplane jumped and twisted up every now and then. All his instruments had stopped working. The radio and compass were both dead. Suddenly, he saw another plane with no lights on its wings. The other pilot gestured him to follow his plane and turned his aeroplane slowly to the north in front of the author’s Dakota so that it would be easier for him to follow. The author was glad to follow him like an obedient child. After half an hour, the strange black plane was still guiding the author in the clouds. Suddenly, he saw two long straight lines of lights in front of him. It was a runaway. He was safe and landed safely out of the clouds. After landing, he went to the control room to find who was the other pilot who saved him. He wanted to thank the pilot but the pilot and his aeroplane both had disappeared. It was a mystery.
