A private plane en route from Spain to Cologne flew over the Baltic Sea and crashed into the sea off the coast of Latvia.
Previously, all contact with the plane was broken off.
According to "Bild" information, a pilot, a man, a woman and her daughter were on board.
As a spokesman for the Air Force confirmed to the German Press Agency on Sunday evening, alarm squads consisting of two Eurofighters rose in German airspace to get an idea of the unusual flight behavior.
According to initial findings, the pilot may have lost consciousness.
"Bild" also reported that the machine reported pressure problems in the cabin after taking off from Jerez in southern Spain.
Accordingly, contact with the ground broke off just behind the Iberian Peninsula.
A squad of the French army took over in the airspace over France, before a squad from Neuburg an der Donau and later from Rostock-Laage took off in German airspace.
