BRUSSELS, Sept. 4 (Xinhua) -- A pilot Sunday fell out of his military helicopter over 1,300 meters high during an airshow for a regiment open day in Amay, in Liege province of Belgium.

The pilot had been confirmed dead after a search for him, according to Belgian media.

A military spokesperson told the VRT that the army was staging a demonstration with parachuting for the open day. Two pilots were on board an Agusta A-109 helicopter when one of the two fell out of the aircraft. The co-pilot managed to grab the control of the helicopter and land it safely after he found the seat of the pilot was empty.

According to the first elements of the investigation, it appears that the pilot, who was not wearing a parachute, might voluntarily jump from the aircraft, taking advantage of a time when his co-pilot was helping the parachuting.

A judicial inquiry has been opened to allow all the data of the dramatic flight to be studied.
