Medical evacuation
[2] In Asia, according to Aeromedical Global (M) Sdn Bhd, medical evacuations via air ambulance can be performed via a single or dual stretched setup.The first medical transport by air was recorded in Serbia in the autumn of 1915 during the First World War.[4] One of the ill soldiers in that first medical transport was Milan Rastislav Štefánik, a Slovak pilot-volunteer who was flown to safety by French aviator Louis Paulhan.[5] The United States Army used this lifesaving technique in Burma toward the end of World War II with Sikorsky R-4B helicopters.The first helicopter rescue was by 2nd Lt Carter Harman, in Japanese-held Burma, who had to make several hops to get his Sikorsky YR-4B to the 1st Air Commando Group's secret airfield in enemy territory and then made four trips from there between April 25 and 26 to recover the American pilot and four injured British soldiers, one at a time.
