Knoll Aircraft Company

Engineering work, stress calculations, and drawings for the first model, the KN-1, were completed in Room 623 of the Broadview Hotel.

[5] Felix and Herbert Schwenke; another German immigrant from The Rohrbach Metal Aeroplane Company, worked on the plans together.

[6] George Siedhoff, who owned and built the Broadview Hotel where the KN-1 was designed, was selected to build a new 50,000 square foot factory on a 148-acre tract of land at the northeast corner of Kellogg and Webb Road.

[8] Assets such as machinery, tools, and equipment were purchased from the bankruptcy of Laird Whippoorwill Airplane Company.

[10] The December 30, 1928 first test flight was so successful that pilot Howard Jones chose to double the planned time and stayed in the air for thirty minutes.

[13] On June 12, 1929, test-pilot Russell Dick flying the Knoll KN-3, beat the US Army's Lieutenant Walker piloting a Thomas-Morse pursuit plane in a race performing at the Wichita Air Show.

On June 2, 1929, the new factory building under construction at Kellogg and Webb road was severely damaged by a storm.

[21] Arguments between the board of directors and management broke out over the necessity of building the new factory, the hiring of too many engineers, and also the Yunker contract work.
