Rafale M jets fly over Lake Assal, the lowest point on land in Africa.
Lake Assal is a crater lake in central-western Djibouti which lies 155 m (509 ft) below sea level.
Here’s is a cool image of two French Navy Rafale M aircraft flying over the lake, one of the most saline in the world: the salinity level of its waters (10 times that of the sea) makes the surface extremely bright.
Although we can’t be sure about the altitude the two French jets were flying, the leading plane in the formation seems to be quite low (check the shadow) over the lake, most probably below sea level.
