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 developmentEdit

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 enclosed cabin. The 47H proved to be too small and the 47J was developed. The "J" model was a single pilot aircraft with the pilot seat and controls position centered at the front of the cabin 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 historyEdit

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]
