If you have the time at DIA (Denver International Airport) take a stroll along the bridge between the main terminal and concourse A. (Most folks take the train, and don't even realize the bridge exists.) There is a display of about 50 (maybe 100) fully-operational scale engines, including a Wankel!

        If you are just there for a connection, keep in mind that you will have to pass though security to get back to the concourses. (Ugh) Be sure you have enough time to marvel over these engines AND go back through security.

        They will be on display until September 10th.
