A sculpture by Belgian born artist "Panamarenko" , pseudonym of Henri van Herwegen(1940). He is famous for his work with aeroplanes as theme; none of which are able nor constructed to actually leave the ground.
Panamarenko studied at the academy of Antwerp. Before 1968 his art was inspired by pop-art, but early-on he became interested in aeroplanes and human powered flight. This interest is also reflected in his name, which supposedly is an acronym for "Pan American Airlines and Company".
