A machine built around 1924, consisting of an egg-shaped fuselage with an underslung gondola and extra-long landing gear that could be found at Stinson Field at the time. A mid-wing monoplane, the 90hp Curtiss OX-5 engine was mounted in a cowl that looked much like a NACA cowl, not then invented, and its radiator was mounted on the outside of the cowl.

The ship was said to be the brainchild of a German inventor, and one named Maer was known to be working at Stinson Field, but other sources credit it to a Prof Warner, who also designed an ornithopter.

 

An Air Service Newsletter lists the plane as "The Fly," designed and constructed by a Lt D B Phillips, assisted by members of the 3rd Attack Group.

 

Reportedly was Charles Lindbergh who labeled it "The Egg" when he saw it.
