Captain Cowgill had always wanted to arrange a hot-air balloon expedition. One day, he placed an announcement in all the morning papers. He wrote that he needed three people who wanted to take a risky adventure. Ten people came to his office and Captain Cowgill selected three of them: two men and a young lady.

The first volunteer was Mr. Crutter, a well-dressed man of about sixty. He looked depressed and unhappy. The second one was a doctor, Dr. Hagan, a sad thin gentleman. The third adventurer, Miss Dermott, looked slim and miserable. They were ready to fly in the balloon in spite of the risks. Though Captain Cowgill hoped for success, there was a great chance that the participants wouldn’t come back.

The next day, the balloon was ready for the journey. They had some food and the gas equipment. It was supposed that the travellers would fly during the day and then land for the night. Right before take-off, a young man ran up to Captain Cowgill and begged to let him join the expedition. Captain Cowgill listened to his arguments and let the young man, Mr. Winden, fly too.

With the last farewell to Captain Cowgill, the balloon went sailing towards the clouds. At first the travellers said nothing. An hour later they found the journey exciting. Two hours later they revealed their reasons for coming on the dangerous flight.

Mr. Crutter said that he had been cheated by his partners and had lost a large part of his business. Though he had enough money left, he felt extremely depressed. Dr. Hagan told the travellers that he had lost his job in a hospital. He felt lonely and unwanted. Miss Dermott said that she suffered from a serious disease and had no money for treatment. Mr. Winden had just split up with his girlfriend and was ready to die.

In the evening, the travellers decided to take a rest. They landed in a deserted place and tied the balloon to a tree. After supper they continue talking about their unhappy fates. Suddenly, Mr. Crutter offered to share his money with his new friends. Dr. Hagan smiled and looked at Miss Dermott. “I think I can cure you, Miss Dermott,” he said. “I have already had patients with the same diagnosis.” Miss Dermott smiled. But it wasn’t the last surprise. Mr. Winden proposed to Miss Dermott saying that he had fallen in love at first sight. She shyly promised to think it over.

The talk raised their spirits and, in the morning, everybody decided to go back home. Now that all their problems were happily solved, they didn’t want to go anywhere. Suddenly Miss Dermott cried out pointingto distant object in the sky. It was their balloon that had broken loose while they were having breakfast. Nobody felt upset!

The group decided to walk to the nearest railway station. Mr. Crutter bought tickets for his new friends and they sent Captain Cowgill a telegram. It said that the balloon had flown away accidentally, their expedition had failed and they would arrive in town the next day.
