You’ll know Liz McClarnon best for being one third of the British girl group Atomic Kitten. She’s since branched out a bit, appearing on television and reality shows, but audiences outside North America may no longer view her as a household name. She earns a spot on this list for the sheer determination she had to overcome her fear of flying. Her fear developed when Atomic Kitten was at the height of its fame, in the early 2000s.
