In February, 2001, CEFAA launched an investigation after receiving reports from air traffic controllers and pilots from the Calama airfield. 

The report was of a UFO moving high (over 50,000 feet) in a general Eastern-Western direction at 2:00 p.m. UTC on February 16, 2001, at an observed speed between 100 and 200 km/hour. The phenomenon was visible for around 30 minutes. 

The sighting was made known by local television channels and caused great excitement. Once the investigation was carried out, analyzing all the available evidence, it was possible to verify that it was a Montgolfier Balloon launched by France’s Air Service of CNRS, in coordination with Brazil for the study of the Earth’s upper atmosphere. 

In 1977, this French organization had the idea of using Montgolfier Infrared Balloons for the study of the upper atmosphere. This globe was built as a 40,000 m3 hot air balloon, heated during the day by the radioactive flow of heat from the sun and at night by the flow of infrared rays emanating from the Earth.

The balloon was launched from the town of Bauru, in Southeastern Brazil, on February 15, 2001, and flew over the city of Calama on February 16 of the same year, causing alarm among those who witnessed the event.

At the time of the balloon overflight, F-5 aircraft were in the area conducting training. They were notified about the presence of the UFO, went to investigate and were able to identify it.

The corresponding trajectory of the Montgolfier globe, which followed the system of circulation of the winds, is reported in the document sent by the French agency and corroborated by Brazil.
