Major William Bryan Robertson (October 8, 1893 – August 1, 1943) was an American aviator and aviation executive who was the co-founder of Lambert-St. Louis Flying Field as well as the owner and President of Robertson Aircraft Corporation (RAC) located there, a company which he had co-founded with his brother, Frank, in 1918.
In 1924, Major Robertson became the first commanding officer of the Missouri National Guard Air Unit 35th Division, Aviation Section operating out of Lambert field with eight Curtiss JN-4 "Jenny" aircraft.

The glider's right wing separated shortly after it had been released at 3,000 feet (910 m) by its Army C-47 tow plane.
