(ALAT), including the Sikorsky H-34, aggregated over 190,000 flying hours in Algeria (over 87,000 for the H-21 alone) and helped to evacuate over 20,000 French combatants from the combat area, including nearly 2,200 at night. By the time the war in Algeria had ended, eight officers and 23 non-commissioned officers from ALAT had been killed. The use of armed helicopters during the Algerian War, coupled with helicopter transports which can insert troops into enemy territory, gave birth to some of the tactics of airmobile warfare that continue today.

The broken blades flew directly into the audience of the airshow killing 8 people and severely injuring and mutilating at least 40 more. Due to the unstable political situation of the country at the time, no investigation followed the accident. Several years later, many irregularities came to light: The helicopter condition was not good when it was purchased by the Uruguayan Navy, fuel used was not appropriate, temperature on the day of the accident was too high to attempt a heavy lift, and the co-pilot of the helicopter was a fixed wing pilot with no experience in rotary wing aircraft. *10 July 2002 Sikorsky S-58ET, N580US (S/N 58-1673, built 1963), struck power transmission lines with its tailwheel, ripping the aircraft in two, over Brookville Lake, Indiana. One crew member was killed; the other two crew members were rescued by boaters. The aircraft was operated by Midwest Helicopter Airways of Hinsdale, Illinois, and registered to Midwest Truxton International of Burr Ridge, Illinois.
