use the remaining horizontal wind tunnel and Twinwoods Adventure use the vertical wind tunnel, previously the Vertical Spinning Tunnel (VST) for indoor skydiving. The VST was converted in 2005 by Bodyflight to be the first indoor skydiving wind tunnel in the UK, and at 16.4ft in diameter remains the largest. On 1 March 2019, Historic England listed the VST as Grade 2 due to its historic and architectural interest. The rest of the building was converted in 2007 and is used by Twinwoods Adventure as a multi-activity centre. Another building on the site is the Yarl's Wood Immigration Removal Centre.
