"This invention relates to improvements in aeroplanes, the principal object being to produce an aeroplane which will control the air instead of the machine being controlled by the air. A second object has been to so construct the aeroplane that the air currents or air pressure against opposite sides of the machine will be equalized and the aeroplane will thereby have great stability. ... The aeroplane is so constructed that the air pressures from opposite sides on meeting or coming together are forced upward, thus being utilized to help raise the machine."
- Tech class CPC B64C23/005: Influencing air flow over aircraft surfaces, not otherwise provided for
- Inventor John Sowell location: Stockton, San Joaquin county, California (FIPSloc=6077); assigned one half to Ernest Sowell of Sacramento, Sacramento county, CA (FIPSloc=6067) (imputed from HistPat)
