The Puget Sound Engineering Council (PSEC) Engineering Fair is held in conjunction with local chapters of engineering societies, colleges, and businesses. The Fair generally has about 25 display booths staffed by practicing engineers and technical people representing many types of engineering disciplines. It provides a fun, visible way for K-12 students to see and hear about the various types of engineering disciplines, encouraging them to think about engineering as a career.

The event is open to the public, with the target audience being K-12 students and their parents. Museum admission is not required to enter the Fair, which is held in the Side Gallery at the Museum of Flight. However, admission is required for entry into the rest of the museum.

The Engineering Fair is an annual event held in conjunction with National Engineers Week. The Fair also features a hands-on design competition on site: The Popsicle Stick Bridge Load Competition sponsored by the American Society of Civil Engineers.
