Speculation as to the Skylon's fate included theories from Jude Kelly, artistic director of the Southbank Centre, that it was thrown into the River Lea in east London, dumped into the Thames, buried under Jubilee Gardens, made into souvenirs or sold as scrap. The base is preserved in the Museum of London and the wind cups are held in a private collection. An investigation was carried out by the "Front Row" programme on BBC Radio 4 and the result was broadcast on 8 March 2011. It was revealed that the Skylon and the roof of the Dome of Discovery had been sold to George Cohen, Sons and Company scrap metal dealers of Wood Lane, Hammersmith, and dismantled at their works in Bidder Street, Canning Town, on the banks of the River Lea. Some of the metal fragments were then made into a series of commemorative paper-knives and artefacts. The inscriptions on the paper-knives read "600" and "Made from the aluminium alloy roof sheets which covered the Dome of Discovery at the Festival of Britain, South Bank. The Dome, Skylon and 10 other buildings on the site, were dismantled by George Cohen and Sons and Company Ltd during six months of 1952."
