In 1930, Boeing created the revolutionary Monomail, which made traditional biplane construction a design of the past. The Monomail wing was set lower, was smooth, made entirely of metal and had no struts (cantilevered construction). Only two examples of the Boeing Monomail 221 were ever constructed, and both managed to find their way into the employ of Wyoming Air Service.
On May 27, 1935, Alva Lucas was piloting this particular Monomail, registration number NC-725W, on a regularly scheduled mail run between Billings, Montana and Cheyenne, Wyoming. At approximately 4:05 p.m. the aircraft impacted terrain near Glendo, Wyoming, killing the pilot and completely destroying the aircraft. Wx in the area was reported as low ceilings with clouds and mist obscuring the tops of hills, along with heavy rain. Eyewitness accounts indicate the pilot was contact flying.
Seventy-two years after the fact an AvAr team from the Colorado field office located this site and conducted a pedestrian survey.
While it is known that most of the wreckage had been removed shortly after the accident, a fairly significant debris field remains to help flesh out the story of this truly unique aircraft's tragic end. AvAr team members are planning a return to this site in 2009 in order to conduct a sub-surface survey.
