Cussac Close Encounter
Two children saw a sphere-shaped UFO, 2 meters in diameter, and "four little devils" on the ground.
One of the humanoid beings was bending over, apparently busy with something on the ground, and another held a mirror-like object. They were observed to levitate before quickly entering the UFO and flying away. The UFO was said to make a soft whistling sound and smelled of sulphur.
The Cussac incident, also known as the Close encounter of Cussac, was a widely-publicized incident in which four aliens and a UFO were seen by two children, 13-year old François and 9-year old Anne-Marie in 1967.
They initially saw four aliens but eventually found a glowing sphere, two meters in diameter. One of the aliens was bending over, and another of the four aliens was holding a strange alien mirror object. The glowing UFO was described as having a soft, whistling sound and smelling of sulfur.
