The History
The phrase originated in the early years of aviation, most likely in the 1930s. Early aircraft were primitive by modern standards, with limited instruments and unreliable gauges. Pilots often had to rely on their own physical senses, including the vibrations they felt through the aircraft's seat, to judge whether the plane was flying straight and level. The feel of the aircraft transmitted through the seat of the pilot's trousers was a genuine source of information, particularly when instruments failed or in conditions where visual references were unavailable.
The expression "flying by the seat of one's pants" began to appear in newspaper and magazine coverage of aviation in the 1930s. One of the earliest printed references appears in a 1938 edition of a Wisconsin newspaper, describing a pilot's account of how early flyers managed without modern instruments. The phrase was used to distinguish instinctive, experience-based flying from the instrument-based flying that was becoming standard as technology improved.
From aviation, the phrase extended naturally into other areas of life. Any situation in which someone had to act without preparation, guidelines, or reliable information could be described in these terms. By the mid-twentieth century the phrase was in wide civilian use, applied to everything from business decisions to parenting to comedy performance.
How It Is Used Today
