 The Millenium Falcon was constructed in a hangar at Pembroke Docks  where great flying boats were made in the 1930s. It was brought to  Elstree studios, London in sixteen interlocking sections by a convoy  of trucks. After reassembly, the Falcon was floated into position on  the then brand new Star Wars stage by means of compressed air pads  similar to those used on hovercraft.
