Recognition (WEFT)
| W — Wings | Low-mounted, straight |

| F — Fuselage | 6.3 m fuselage |
| T — Tail | Twin fin |
WEFT is AircraftIQ's four-point recognition method — how it works.
Spot it by:
- Low-wing cantilever monoplane
- Twin tails
- Two piston engines in nacelles on the wings
It was a conventional low-wing cantilever monoplane with twin tails and a tailwheel undercarriage, with an engine nacelle on each wing.
Specifications
- The Langley 2-4 Twin has a length of 6.3 m (21 ft).

History
It was named in honour of Samuel Pierpont Langley and designed to avoid strategic materials, with its structures built up from mahogany veneers bent over moulds and impregnated with resins. Once the United States entered the war the resins proved to be in shorter supply than metal, and the project was abandoned.
Variants
Two prototypes were built, one with 65 hp engines and one with 90 hp engines. The second was evaluated by the United States Navy as the XNL-1.
Where you'll see it
The Navy did not order the type. The XNL-1 was sold as war surplus and, after an accident in 1965, parts of it were used to build a one-off homebuilt aircraft named the Pierce Arrow.
