The Lawson L-4 was a 1920s American unflown biplane airliner, designed and built by the Lawson Air Line Company of Milwaukee, Wisconsin.

Design and development

In 1924 the Lawson Air Line Company had a need for an airliner to use on the night service between Chicago and New York. The L-4 was a three-engined biplane airliner which was fitted with sleeping berths, lavatory and unusually a shower unit. When the aircraft was preparing for its first flight the aircraft got stuck on soft ground, in an attempt to taxi the aircraft from the soft ground it was severely damaged. Before the aircraft could be repaired and flown the company folded.
