Morrow 1-L

08/31/2012. The Morrow Aircraft Corporation was formed by Howard Morrow at San Bernardino, and a new plant was erected on the San Bernardino County Airport. The Company went into operation on April 1, 1941, developing a two-seat training monoplane suitable for use under the Civilian Pilot Training Program. In order to eliminate the use of strategic materials a plastic-bonded plywood construction was used. The prototype, also referred to as Victory Trainer, was completed in the late Summer of 1941, however, no production followed. Here the data from the Jane's 1941 issue:
