Carol obtained her pilot's licence two years ago and will be flying a Diamond DA42 twin-engine propeller plane nicknamed Mildred.

As she anxiously heads towards her challenge, she has been going full throttle with her training, most recently her plunge into the ocean. 

She was pictured in a life jacket with a helmet as she prepared for the possibility of dropping into water from the plane. 

After emerging from her terrifying dip, the stunning star could not stop smiling, seemingly invigorated by the plunge.

She said: 'My life's dream has been to be a pilot. I fought to get to Cambridge University as a comprehensive kid on free school meals in the 1970s.

'I was the first child from my town to get there. My drive was always because I wanted to be a pilot but the RAF wouldn't train women as pilots back then and we were a poor family so flying lessons were out of the question and my dream was put on hold,' she continued.

'Only when I got into my 50s have I had the proper opportunity as a single parent to put everything else on the back burner.'
