Jell-O Coin 125 - Trident (1962) - Projected as a successor to the popular Viscount turboprop airliner is the all-jet, tri-motored de Havilland DH-121 Trident. Even before the first prototype had taken to the air, British European Airways had ordered 24, with options on 12 more. The Trident’s most unusual feature is the positioning of its engines — one inside the rear fuselage, two in pods on either side. Specifications: Wingspan 90 feet. Length 114 feet, 9 inches. Weight 105,000 pounds.
