The West German army is testing a secret new military reconnaissance plane made almost entirely from synthetic materials, the news magazine Der Spiegel reported Sunday.
It said in a report made available ahead of today's publication that the single-engine, one-seater plane had made its maiden test flight near Ingolstadt in the south of West Germany on June 24.
The Defense Ministry refused to comment.
Spiegel said the plane's fuselage and wings were made from synthetic materials, making it virtually undetectable by conventional radar. It did not give the source of its information.
