An orange cloud over Bagnères-de-Bigorre

Summary

On May 22, 2017, a witness in Bagnères-de-Bigorre observed an unusual orange cloud in the sky towards Tarbes. Initially thought to be an airplane contrail, the unusual shape and thickness intrigued the observer, who took photographs and contacted local authorities. No other witnesses were found. After analyzing the images and the described features, GEIPAN investigators considered the possibility of fuel dumping by an aircraft. This hypothesis aligned with the observations, though no public records confirmed it. The conclusion was that it was likely a jet fuel release from a military aircraft at high altitude, to minimize environmental impact.

The case was classified as "B," indicating a probable observation, supported by precise testimony and coherent photographic analysis. Although no operational records of the fuel dump were found, the lack of military logs and the visual consistency support the hypothesis. This case illustrates how unusual aerial phenomena can fit conventional explanations when rigorously analyzed.
