I have an uncle who was a pilot, and he used to fly passengers and cargo to and from Honduras. Once he had to fly the body of an extremely overweight woman back to Honduras. She was so large they had to take the top off the casket and place it on its side next to my uncle, the pilot. According to him, as the airplane gained altitude, it forced air from the woman’s lungs and she groaned. He always carried a sidearm and he pulled it and told the woman that if she moved he was going to kill her again!
