What You'll Learn
The fuel tank was placed in front of the pilot
The fuel tank of Lindbergh's aircraft, the Spirit of St. Louis, was placed in front of the pilot. This arrangement improved the centre of gravity and reduced the risk of the pilot being crushed between the main tank and the engine in the event of a crash. This design meant that there could be no front windshield, resulting in limited forward visibility. However, Lindbergh was accustomed to flying in the rear cockpit of mail planes with mail bags in front, so he was unconcerned by the lack of a front window. When necessary, he could slightly yaw the aircraft and look out the side window or use the periscope that was installed to provide some forward vision.
The placement of the fuel tank in front of the pilot was a critical decision influenced by several factors. Firstly, Lindbergh prioritised maximum fuel capacity and minimum aerodynamic drag for his transatlantic flight. Positioning the fuel tank at the centre of gravity helped maintain balance and eliminated the need for fuel transfer between multiple tanks during the flight. This simplified the fuel management system and reduced potential failure points.
Furthermore, the fuel tank acted as an ironic firewall, providing additional protection for the pilot. In the event of a crash, the fuel tank's position in front of the pilot helped safeguard Lindbergh from being crushed by the engine. This design consideration was particularly relevant given Lindbergh's concern about cracked fuel and oil lines, which had caused issues in other long-distance flights.
The Spirit of St. Louis was modified to accommodate the weight of the extra fuel required for the journey. The fuselage and wingspan were lengthened, and the plane was structurally reinforced. The engine was moved to the front, and the cockpit was relocated to the rear for safety reasons. These modifications allowed the aircraft to carry more than 450 gallons of fuel, weighing 2,700 pounds—more than double the weight of the plane, engine, and pilot combined.
Lindbergh's focus on maximising fuel efficiency and minimising weight was evident in other aspects of the aircraft's design. He eliminated unnecessary weight, even cutting the top and bottom off his flight map. He opted not to carry a radio due to weight considerations and the unreliability of radios during that period. Additionally, Lindbergh did not include brakes or a pilot's parachute in the aircraft's design.

The fuel tank was placed at the centre of gravity
The fuel tank of Lindbergh's plane, the Spirit of St. Louis, was placed at the centre of gravity of the aircraft. This decision was made to improve the centre of gravity and reduce the risk of the pilot being crushed between the main tank and the engine in the event of a crash. Placing the fuel tank at the centre of gravity also minimised trim changes that would otherwise occur when fuel was consumed, eliminating the need for fuel transfer between various tanks during the flight.
Lindbergh's plane was modified for his long journey from New York to Paris. The plane needed to accommodate the weight of the extra fuel, so the fuselage and wingspan were lengthened, and the plane was structurally reinforced. The engine was moved to the front of the aircraft, and the fuel tank was placed at the centre of the plane for balance. The cockpit was relocated to the rear of the plane for safety.
To keep the weight of the plane down, Lindbergh removed unnecessary items, such as the radio and the pilot's parachute. The fuel tank was placed in front of the pilot, along with the oil tank, acting as a firewall to protect the pilot in the event of a crash. This placement meant that there could be no front windshield, limiting the pilot's forward visibility. However, Lindbergh was accustomed to flying in the rear cockpit of mail planes with mail bags in front, so this was not a concern for him.
The Spirit of St. Louis was powered by a 223 hp, air-cooled, nine-cylinder Wright J-5C Whirlwind radial engine, which was exceptionally engineered by Charles Lawrance.
