In November 2015, a witness in Leguevin filmed several objects in the sky. Two appeared to be airplanes—one flying high with contrail and another lower without, matching Flightradar data. A spherical object raised attention, and analysis suggested it was likely a thermal balloon. Its angular size and position indicated it was at about 1 km altitude, explaining its curved trajectory. Wind patterns in the area supported this theory, as the change in direction with altitude explained the observed movement. Although not definitive, the case was classified as B due to the high probability of being a thermal balloon.
