On June 5, 2015 at 9:10 PM, a witness observed from their balcony on the 4th floor the presence of two phenomena of round shape and dark color in the clear sky. The first UAP seems rather stable, the second moves slowly in an arc with the first object as its center. The witness films the phenomenon at length, then decides to take their car to get closer but loses sight of the objects (the witness's videos will be posted on the site later due to a temporary technical problem). Only one testimony was collected. The shapes discernible in the videos strongly suggest two hot-air balloons (or possibly gas balloons) whose basket would not be optically separated from the balloon due to the distance. The two-body aspect (balloon + basket) is supported by a radiometric analysis (specialized software IPACO). The two trajectories partially reconstructed (from the video and the ground landmarks appearing in it) are fairly similar, except for a loss of angular height of one of the two shapes. These trajectories can at some point give the illusion (witness's perception) that one shape is turning around the other. These trajectories are consistent with objects carried by the wind, with a constant drift to the left of the witness. The decrease in altitude of both shapes is consistent with the need to land before nightfall (according to regulations). See the investigation report. It was not possible to finalize the exact identification of the devices involved; however, a large majority of the descriptive parameters from the visual observation and from the videos converge perfectly toward this simple and plausible explanation. The probability of a flight departing from Kehl (or even Offenburg) is high. Indeed, there are tourist flight companies in that area, which is in the direction of the observation and at a distance compatible with the observed size of the hot-air balloons in the video. The strangeness is therefore very low, and although there is only one witness, the consistency remains fairly strong because the videos confirm their observation and allow a very objective approach to the observed phenomenon. Consequently, GEIPAN classifies this observation as A: observation of hot-air balloons.
