Still Champagne    (April Fool's Day - 1992)

Virgin Atlantic ran an advertisement explaining that "a recent tracking study by the Institute of Aeronautical and Atmospheric Studies reveals that the waste gases from champage (CO₂ + NO₁) can have a detrimental effect on the upper atmosphere and contribute towards the depletion of the ozone layer."

For which reason it had commissioned a special "still champagne" to serve on its flights. It promised that the taste was "distinctively dry with a hint of flint."
