Steffen Monoplane
The exact identification is disputed, but in the source of the photo it is identified as the “Steffen-Falke 1911”, powered by a 50 hp Argus engine, built for Heine, which crashed on its first flight. The builders of the Zanonia-winged monoplane were the Steffen brothers of Kiel.

Steen Steenship
LaMar Steen’s first airplane was a two-place, low-wing design named the Steenship. The Steenship has wooden wings, a tube-and-fabric fuselage, and originally sported a many-coat nitrate dope covering job. The modified O-290-G engine produced 140hp and gave the plane a very respectable cruise speed of 165 mph. In addition, it was stressed for aerobatics (+/- 9 G). Construction took 3-1/2 years and cost $3,800.
It first flew in July 1966 as N881LS. No plans were ever made available for the Steenship, and no original blueprints or construction drawings exist today.
The May 1989 issue of Sport Aviation had an article about Bob Leonard’s restoration of the plane in Healdsburg, CA. In mid-2002, Burt Nichols in Arkansas purchased it (still retaining the original registration number N881LS) and flew it regularly. After 200 hours in the first 9 months he decided to upgrade the original Lycoming O-290 to a Lycoming O-320. As of July 2003, it was very close to first flight with the new engine.
In late Jan. 2005, it was in the process of a rebuild.
