I recently sat next to a member of HCGB who had been down to London with the Secretary of the HCGB to see the sports minister or the transport secretary (can't remember which) to discuss this very subject.
Apparently, at the moment, there is more chance of finding other intelligent life forms in the solar system. Allegedly, its the Mayor's decision and he is apparently very heli-unfriendly.
Pathetic!
