The Bell 47J Ranger is an American two-bladed, single engine, light helicopter that was manufactured by Bell Helicopter. It was an executive variant based on the highly successful Bell 47 and was the first helicopter to carry a United States president.
Design and development
The 47J was a four-seat variant of the earlier three-seat Bell 47H. The 47H was a deluxe variant of the 47G with a fully clad fuselage and an enclosed cabin. The 47H proved to be too small, so Bell developed the 47J. The 47J was a single pilot aircraft with the pilot seat and controls centered in the front of the cabin, and positioned close to the 180° view unobstructed Lexan "bubble" windscreen. A single bench seat at the rear of the cabin spanned its entire width and allowed for a passenger capacity limited by weight to typically 3 or 4 adults.
Operational history
In March 1957 two Bell 47Js were bought by the United States Air Force as presidential transport and designated H-13J.[1] On 13 July 1957 a H-13J was the first helicopter used by a United States president when it carried Dwight D. Eisenhower from the White House.[1] In March 1962 the two helicopters were moved from presidential duties but were used as VIP transports for the next five years until retired in July 1967.[1]
Two Bell 47J-2s were used during the 1966 film production of Paradise, Hawaiian Style starring Elvis Presley. Throughout the film Presley's character, Rick Richards, was flying a Bell 47J-2 over the Hawaiian Islands.
