Preliminary data based on the notification from the Belgium authorities:
Reportedly, the aircraft took off at 16:15 UTC. A couple of minutes later it was seen flying at low altitude by some pedestrians in Lasne, about 8 NM north of EBBZ. The witnesses declared that he was overflying the country road, Chemin de Camusselle in a northeasterly direction at low altitude. One of the pedestrians even saw an occupant waving. The aircraft subsequently made a left hand climbing turn after which the left wing suddenly dropped and the aircraft went into a dive. The aircraft hit the ground almost vertically and immediately took fire.
