The Stout 1-AS Air Sedan was an all-metal monoplane that was an early example in the Ford Trimotor lineage.
[1] William Bushnell Stout, having just completed his famous letter writing financing effort for the company, embarked on a new aircraft using the "thick airfoil" batwing design, combined with all-metal construction employed overseas in Junkers aircraft.
The pilot and co-pilot sat side-by side, in an open cockpit mounted in the leading edge of the wing.
The airfoil's chord stretched half the length of the fuselage, like the earlier batwing.
On one test flight, Lees and the lead engineer, George H. Prudden, took off with Stout as a passenger; they barely kept aloft, and landed in a neighboring field.
