Aeromedical evacuation (AE) usually refers to the use of military transport aircraft to carry wounded personnel. The first recorded British ambulance flight took place in 1917 in the Sinai peninsula some 30 miles south of El Arish when a Royal Aircraft Factory B.E.2c flew out a soldier in the Imperial Camel Corps who had been shot in the ankle during the raid on Bir el Hassana. The flight took 45 minutes; the same journey by land would have taken some 3 days.
