About the 1903 Wright Flyer

The 1903 Wright Flyer, built by Wilbur and Orville Wright, made its first flights on December 17, 1903, at Kitty Hawk, North Carolina. It is a canard biplane of wood and muslin with a 12-horsepower engine driving two pusher propellers through chains. The Smithsonian gives its wingspan as 12.3 m (40 ft 4 in) and its empty weight as 274 kg.

  • Orville Wright made the first flight on December 17, 1903: 12 seconds covering 36 m (120 ft). [1]
  • The fourth and last flight that day, flown by Wilbur, covered 255.6 m (852 ft) in 59 seconds. [1]
  • A single 12-horsepower, four-cylinder Wright engine drove two pusher propellers through a sprocket-and-chain transmission. [1]

How many fit?

  • ≈ 7.3 × Human · height lined up end to end match the Wright Flyer (1903) · wingspan
  • ≈ 3.3 × Human · body mass on the scales weigh as much as Wright Flyer (1903) · empty weight
  • ≈ 2.5 × Car · length lined up end to end match the Wright Flyer (1903) · wingspan

Counts divide one sourced figure by another. "End to end" uses each object's main measurement; weight and volume rows appear only when both figures are sourced.

Factors compare the wingspan of the 1903 Wright Flyer with each object’s own main measurement (height for a human). Where a size varies, the factor is given as a range.

Notes on these figures

  • The Smithsonian page does not say what the 341 kg gross weight includes beyond the empty airframe.
