The flight plan never ends.
We collect, restore and display the history of United Airlines and its predecessor carriers, so the next generation of aviators knows where they came from.
See the DEN Historical Exhibit
A permanent exhibit inside United’s Flight Center in Denver, with a research library, A/V room, uniforms, models, a Link Trainer and a 9/11 memorial.
The Exhibit is not open to the public without an advance appointment. United employees with badge access to DENTK may visit at any time.
