Boys from Haarlem drew a ''secret'' picture of a British airplane

About

Alarming reports of espionage appeared in the British press: the construction secrets of one of Britain's newest jet fighters, the Vickers Supermarine "Swift", had been leaked and published in a Swiss aviation magazine. However, two 23-year-old twin brothers from Haarlem, Robert and Rudolf Das, appear to have made the drawings on the basis of previously disclosed and published data. SHOTS: - English and Dutch headlines; - shots of the secret drawings showing details of the plane and the jet engine; - the Das brothers sitting in their room, at home, bent over their drawing tables working on construction drawings of openwork planes; - the Das brothers addressing the viewers saying that they had done nothing more than combine already known data and that they did not understand anything of the commotion created.

Human-made No record of this work says a model made it. What this means.
