Tau Omega. Tau Omega () was an American professional fraternity for aeronautical engineering. It was established at the University of Oklahoma in Norman, Oklahoma in 1927. Tau Omega was the first professional fraternity for aviation. In 1953, it merged with Gamma Alpha Rho to form Sigma Gamma Tau, a national aeronautical engineering society.

History 
Tau Omega was established as a professional fraternity in December 1927 by students who were interested in flying instruction at the University of Oklahoma. Its founders were Warren E. Daniel, Orville Gulker, James E. "Jimmie" Haizlip, J. Court Hayes, and Earl O. Weining.

Tau Omega was the first professional fraternity for aeronautics. Haizlip was its first president. Its purpose was promoting an interest in aviation amongst college men. Membership was open to students studying aviation.

By January 1928, students at three other universities had petitioned to form a chapter of Tau Omega. In February 1928, the fraternity was chartered as a "National Honorary Aeronautical Engineering Fraternity". In 1932, Beta chapter was established at the University of Wichita.

The fraternity expanded to include nine chapters and more than 1,000 alumni. On February 28, 1953, it merged with Gamma Alpha Rho, a similar organization, to form Sigma Gamma Tau.

Symbols and traditions 
The fraternity's insignia was a key shaped like a Maltese cross, with a superimposed airplane engine and propellor. On the horizontal arms of the cross were the Greek letters  and . One the vertical arms of the cross were a covered wagon and lamp of learning on the cross, symbolizing the pioneering spirit and knowledge required for the field of aeronautics.

Tau Omega's motto was Quid Pro Quo. Its magazine was The Contact.

Its pledges were required to wear goggles and a white flying helmet the day before being initiated as members. Its initiation traditions included a daybreak airplane ride.

Activities 
As early in as 1927, Tau Omega started the first flying school in Norman, Oklahoma; the school was not connected to the University of Oklahoma which started its own flying school in 1940.

Tau Omega members built and tested airplanes. In March 1928, members of the Alpha chapter rebuilt an airplane that belonged to the Oklahoma Air Transport Company. In December 1929, the fraternity began constructing a glider with hopes of setting a new endurance record. The glider was featured at an aerial display at the University of Oklahoma in March 1930. In April 1931, the fraternity began designing and building a monoplane to be completed in December.

In October 1931, the fraternity built a wind tunnel to be used by University of Oklahoma students for testing miniature airplane models. Members also studied engines, including a Curtis D-12 airplane engine that was loaned to the fraternity by the United States Navy in May 1933.
