On July 1, 1925, James DeWitt Hill taxied into position at Hadley Field, New Jersey, to fly the inaugural eastbound night leg of the nation’s first continuous, scheduled transcontinental airmail service. While Postmaster General Harry S. New looked on, hundreds of spectators lined the field, turning on their car headlights to supplement the airfield’s unreliable lighting and cast a makeshift glow across the runway. Hill’s departure was not a solitary journey, but the opening link in a highly coordinated, multi-pilot relay designed to keep the mail moving across the continent without stopping for darkness.
The success of this 24-hour service depended entirely on the newly installed Transcontinental Airway Beacon System, a chain of rotating lights spaced just three to ten miles apart to guide pilots through the dark. The system was still developing and required immense pilot endurance; if blinding weather obscured consecutive beacons, aviators were left flying completely blind. The extreme peril of the route was proven that very night when Hill’s westbound counterpart, Dean Smith, ran out of fuel and crashed into an Ohio field in the pitch black, highlighting the razor-thin margin between a successful delivery and disaster in the early days of commercial aviation.
