This American woman had already made about thirty parachute jumps when she jumped out of a plane on September 25, 1999, at an altitude of nearly 4400 meters. However, when she realized that her parachute was defective, she struggled to get rid of it and to activate the emergency one. The latter opened only 200 meters from the ground: Joan Murray fell to the ground at a speed of 130 km/h... If the impact did not kill her, it was because the American had just landed on a huge anthill, relatively cushioning her fall. The ants in question: Solenopsis invecta, commonly known as "fire ants", renowned for their venom, which is among the most painful in the world. One might think that fate is getting the better of poor Joan, but in reality, it is the ants' bites that will save her life.
