The Lockheed JetStar (company designations L-329 and L-1329; designated C-140 in US military service) is a business jet produced from the early 1960s to the 1970s. The JetStar was the first dedicated business jet to enter service, as well as the only such airplane built by Lockheed. It was also one of the largest aircraft in the class for many years, seating ten plus two crew. It is distinguishable from other small jets by its four engines, mounted on the rear of the fuselage, and the "slipper"-style fuel tanks fixed to the wings.

Development

The JetStar originated as a private project within Lockheed, with an eye to winning a United States Air Force (USAF) requirement that was later dropped due to budget cuts. Lockheed decided to continue the project on its own for the business market

Design

The JetStar has a fairly typical business jet design layout, with a swept wing and a cruciform tail. The wing has a 30° sweepback and features large fuel tanks at about half-span, extending some distance in front and behind the wing. The wings hold 10,000 pounds of fuel, and each slipper tank holds 4,000 pounds of fuel for a total fuel load of 18,000 pounds. The wing also includes leading edge flaps (not slats) along the front of the wing outboard of the tanks (these leading edge flaps reduce the stalling speed by an additional three knots), while double-slotted trailing edge flaps span the entire rear surface inboard of the ailerons. The wing incorporates inflatable rubber deicing boots for the removal of ice accumulated in flight. The horizontal stabilizer is mounted nearly halfway up the fin to keep it clear of the engines' jet blast..

The first prototype served as the personal transport of Lockheed's Vice President of Advanced Development Projects Kelly Johnson for some time. Elvis Presley owned two JetStars at different times; the second was named Hound Dog II and is on display at Graceland.
