On Friday, May 20, 2016, a mission is carried by the French gendarmerie in the Vignemale Massif in French Pyrénées. The crew took off at 11:40 from Tarbes to perform a mission to deposit and pickup soldiers in the mountains.

After the second pick-up, the helicopter flew very low through the Gaube corridor, hits with the main rotor blades the relief of the mountain and the helicopter crashed.
​
Flight Data could be retrieved but the data of the final flight maneuver was missing. This data was reconstructed with iwi® based on the video-material of a GoPro-camera, that recorded the flight from the take-off position.
​
In addition the pilots-perspective was visualized with iwi® to support the analysis of pilots visibility and potential human factor causes.
