We spent 3 days in Hood River, and one afternoon here at the WAAAM. Neither of us would consider ourselves a car or airplane expert, but we both had a great time ambling through this very well displayed museum.
Beauty is in the eye of the beholder, and I saw this one plane, a Waco brand plane, that was just the most beautiful plane I've ever seen.
By seeing the progression of the engineering from one year to the next, I could follow what was changed from one plane to the next.
Be sure to watch the 10 minute video about the re-enactment of the 1912(?) flight off of a downtown Portland building. In the documentary, the pilot recounts how close he was to NOT lifting off after a short take-off and how close he was to NOT walking away from this one.
