Margaret Fairweather (23 September 1901 – 4 August 1944) was a British aviator and one of the first eight women members of the Air Transport Auxiliary (ATA).

[4] She was known as one of the First Eight, alongside Joan Hughes, Margaret Cunnison, Winifred Crossley Fair, Mona Friedlander, Gabrielle Patterson, Marion Wilberforce, and Rosemary Rees, under the command of Pauline Gower.

[6] Shortly after the death of her husband, Douglas, piloting an ATA aircraft on 3 April 1944, she died in a crash on 4 August that same year; also on board was her sister Kitty who was injured.

[7][8] Because of the lack of fuel Margaret was obliged to make a forced landing at Hawarden in Cheshire which went well until they hit a ditch and she lost control as the Percival Proctor flipped over.

[9] A bus company in Hatfield named its eight buses after the "first eight" of the Tiger Moth pilots in the ATA, including Fairweather.
