Just imagine the difference working antigravity technology would make to our world - perhaps almost effortless travel - at enormous speed. In this presentation, we ask has working antigravity technology been developed? Is it already in use?

We take a look at the evidence from the last 100 years (arguably longer) and consider the reasons for what looks like a comprehensive cover up. In the process we will cover the experiments of Thomas Townsend Brown and John Hutchison and the incredible Coral Castle and the secret Aurora Aircraft development Programme.

Andrew Johnson presented "The Case for Antigravity" on Saturday 7th August, 2010 at the Leeds Exopolitics Expo.
