摘要
| 描述 |
Date: c.1934 (not 1920) Object number: A.2010-4 Medium: paper; photo-emulsion Dimensions (Unframed): 8" x 10" Description: Keystone B-6 (not De Havilland), of the US Army Air Corps. In their drive to open up a transcontinental flyway, postal officials were constantly seeking better, faster aircraft for their pilots to use. When a determination was made to reconfigure the de Havilland aircraft by adding a second engine, postal officials believed they had found their airplane. The first trips were the only successful ones for this airplane. Soon reports were flooding Air Mail Service headquarters of crashes and mechanical problems with the airplanes. After a series of fatal crashes the twin de Havillands (sic) were removed from service. A fuel truck and three unidentified men are in the foreground of this airmail plane in the snow.
