[1] Born Sheila Christine Hopkins in Worcester, Worcestershire, England,[2] she had a turbulent childhood and did not do well at the Alice Ottley School, nearly being expelled several times.

[6] In May 1965 the Piper Aircraft company loaned their Piper Comanche 400 European demonstrator N8515P (named Myth Sunpip) to Sheila, enabling her to set a number of European speed records for its class, such as return trips from London (RAF Northolt) to The Hague, Brussels, Dublin, and Belfast.

[7][8] In April 1966, she obtained another Piper Comanche, this time a 260B registered G-ATOY (named Myth Too) in which she set many of her records.

[9] It was in this aircraft that she made her first solo round the world flight, departing London Heathrow on 18 May 1966 and returning on 20 June 1966, having covered approximately 31,000 miles (50,000 kilometres) in 189 flying hours over 34 days.

[13] Scott was plagued by technical problems during the race, and was stranded for several days due to broken navigational equipment.

[20] Mythre was returned to the Piper factory in Lock Haven, PA where it was one of over a hundred planes damaged beyond repair in a flood in 1972.

These include: She was the founder and the first governor of the British branch of the Ninety-Nines, an association for licensed women pilots which had been created by Amelia Earhart.
