# Bell 47J Ranger

The Bell 47J Ranger is an American single-engine single-rotor light helicopter manufactured by Bell Helicopter. It was an executive variant of 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. 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. 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.
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.
