The Museum of Flight, Seattle, WA, will mark the anniversary of the Boeing 777 entering airline service with a June 7 program dedicated to the aircraft’s history, development, and impact on commercial aviation. Called “Triple Seven Sunday,” the event will feature documentary screenings and a discussion with former Boeing executive Alan Mulally and airline captain Dan Dornseif, co-authors of Boeing 777: People “Working Together” to Produce the Triple Seven. The program coincides with the 31st anniversary of the aircraft entering service and will focus on the development of one of Boeing’s most successful widebody airliners.

Mulally served as director of engineering and general manager during the original 777 development program, while Dornseif is an airline pilot and aviation author. Their book draws on interviews and material from engineers, pilots, and others involved with the aircraft’s creation. A “Meet the Authors” discussion is scheduled for 3:30 p.m. and will be moderated by retired Boeing historian Mike Lombardi. Organizers said the conversation will focus on behind-the-scenes stories from the aircraft’s development and will conclude with an audience question-and-answer session.

Earlier in the afternoon, visitors can attend a screening of First Flights – The Jet Age: 777 from 2 p.m. to 3:15 p.m. The author discussion will run from 3:30 p.m. to 4:15 p.m. and will conclude with a short video presentation about the 777X. Now, a little about the 777; the Boeing 777 first flew on June 12, 1994, and became Boeing’s first commercial aircraft designed entirely using three-dimensional modeling software. It was also the company’s first airliner built with fly-by-wire controls. Today, the aircraft remains one of Boeing’s best-selling widebody designs and continues to serve airlines around the world. The museum said access to both the film screenings and the author discussion is included with regular admission, while museum members can attend at no additional cost.
