Watch Doug Aitken's mirrored hot air balloon take flight
This captioned movie shows Doug Aitken's 30-metre-tall New Horizon hot air balloon, which has a semi-mirrored body, take flight across the skies of Massachusetts.
Called New Horizon, the nomadic installation will pass over several sites in the US state that are managed by the Trustees, which is a non-profit preservation and conservation organisation.
LED lights are hand-sewn throughout the material, which Aitken developed with NASA, and can be choreographed to illuminate in different patterns and colours during the night time.
The balloon will visit and land in several rural locations, where a programme of talks and performances will take place.
