Some recent space history
'In full sincerity and without the slightest hint at irony, the Russian
scientists boasted of the "environmental cleanliness" of the rocket they
were trying to sell. "American shuttle flights and French Ariane launchings
are destroying the ozone layer, but our 'Energiya' and 'Zenit' rockets were
designed to be ecologically harmless," claimed Valery Burdakov and
Vyachislav Filin several years ago.'
