Air Comet

Spanish babes strip for wages | The Sun |NewsAIR stewardesses grounded by a British judge have stripped off for a saucy calendar in a bid to get back missing wages.
Spanish-based budget airline Air Comet went bust last December after the High Court in London ordered the company to stop using its planes and selling tickets.
Stewardesses employed by the firm decided on their naked protest after failing to get up to eight months of unpaid salaries.
More than 1,000 calendars featuring nine women in their flight caps, gloves and high heels have gone on sale for £13.

Not exactly a charity, but close enough...
