The Eagle, only retrospectively designated Model 19 by Curtiss, was a 1919 airliner with a nicely crafted fuselage seating eight people, including the one or two pilots. It was originally a trimotor. The Eagle II was a twin and the Eagle III was powered by single 400-hp Liberty engine. Only a few Eagles were built, the only customer being the US Army Air Service which bought three Eagle IIIs. Optimistically called a 'hospital ship', s/n 64243 was equipped as a four-litter ambulance, but crashed on 28 May 1921. The pilot and all six passengers were killed.
