Doesn't have to be specific. Just keep the Great Liquid Threat ramped up and his kind of general business will naturally increase, or at least maintain status quo.

We have yet to see a test carried out by a completely independent body. One that does not have a vested interest in 'security' (ie. DHS or DfT), or in direct profit therefrom. I don't know who approached whom for this particular demonstration, but I personally don't trust either the media or a business which has a dog in the fight.
