Once again, Ryanair has released their annual charity calendar with proceeds going to Polish charity TVN Foundation.
The notorious calendar, which includes female members of Ryanair's cabin crew in little more than bikinis, hopes to raise €100,000 ($131,000) for the charity, which would bring the calendar's multi-year total to around €600,000, according to the airline.
The calendar is available for purchase on Ryanair flights or through TVN Foundation for £10 ($16).
Check out some of the racy shots from the 2013 calendar, as well as previous years, below.
