I like Ron Glover's Summary:
I have enjoyed my Eindecker fully. It has taught me things that few other airplanes could have. She's docile when she needs to be, yet sprightly when you want her to be. I once heard an old fighter pilot say, "An airplane is like your wife. You love the good points and learn to live with the bad." This is one airplane that is way short on bad points. If you treat her with a little respect, she'll take good care of you and take you places few people can only dream of.
