|The following are operators of the Sikorsky H-19 and Westland Whirlwind helicopters.
Sabena operated S-55s from 1953.[1]
This airline, founded in 1949, used modified Sikorsky S-55 to carry mail and cargo. Later they used helicopters designed specifically for the civilian market.
BEA experimented briefly with scheduled services using the Westland Whirlwind. When these proved unprofitable, the helicopters were relegated to charter services. A BEA Whirlwind appears in the film A Hard Day's Night.
