Is Land was and still is a 7M floating island sculpture made to hover above the Cambridgeshire countryside at this years Secret Garden Party. It danced in limbo like a shaggy Eden, being tossed by the wind or suspended silently. It was one of the core installations at the 2011 art-orientated festival.
It was about to make its final pilgrimage to Burning Man festival where it would float again in the Nevada desert, US. However it was cut down in its prime. Witnesses saw a small group of malicious festival goers, two in a dingy, cut all five tether ropes holding the helium structure at 3am on the Sunday morning of the Secret Garden festival allowing it to float away. The daring £9000, six month project by RCA graduates Sarah Cockings and Laurence Symonds simply floated off into the atmosphere, leaving them completely deflated.
The UK Civil Aviation Authority, local airports as well as chartered air spaces were informed, and attempts have been made to calculate the wind speed and direction around Huntingdon, Cambridgeshire at the time of its release, any more accurate location updates will be published. However due to there being release valves on the balloon, the helium will have been slowly expelled over a long period of time, as opposed to rising quickly and rupturing, meaning the island could have reached great heights.
But what goes up must come down, so the hunt is on. If what looks like a floating chunk of earth turns up in your Nan’s back garden, or if you think you see a new planet on your Easyjet flight to Portugal, please don’t hesitate to get in touch. Is Land is made of durable polyurethane with foliage décor and so, if found, can be repaired and go on to make its maiden voyage to the US of A.

Possible sighting?
^ I thought the same thing at first Emmy, but I re-read his report and it is way different than what the island looks like - and the UFO was full of bright lights.
I hope you guys get your is land back in one piece BTW.
