Page 3 of the April 10, 1939 S.S. Aquitania letter. Lindbergh cites Pan American Martin flying boats being icebound in Baltimore and notes freezing spray hazards on takeoff, concluding that commercial aviation will ultimately adopt multi-engine landplanes for northern transoceanic service. He notes the importance of airport runway lengths and expresses enthusiasm that Hall is actively researching assisted takeoff mechanisms to solve this challenge.
