Today is the 53rd anniversary of the Boeing 727’s first flight. What a day. At the time, the 727 was a risk and important to the success of Boeing. Luckily for everyone, not only was the first flight a huge success, but the aircraft would go on to help redefine domestic air travel.

Its three iconic engines also helped to build aviation fans around the world; it is still a favorite among AvGeeks today. To help celebrate the first flight’s anniversary, we reached out to Boeing to see if we could get some photos, and they delivered! We were told that some “haven’t seen the light of day in 50 years.” Rock on!
