For a long time, we've thought that a flight on London in the Sky is the most fun you can have without taking your clothes off. But actually, we have been asking people to do just that: to take a flight with us on 30 April, get completely naked, and raise awareness and funds for Coppafeel! charity.

Bottoms Up is a brunch to bare all and this brilliant group of ladies have bravely volunteered to get starkers 100ft while in the sky

CoppaFeel! are the first UK breast cancer charity to create awareness amongst young people, with the aim to install a new healthy habit that could one day save a life. They are on a mission to stamp out late detection of breast cancer and ensure the nation is checking their boobs regularly. They want to educate people on the signs and symptoms of breast cancer, encourage them to get to know what is normal for them and empower young people to have the confidence to see a doctor if they notice anything that isn't right for them.
