OK, the heck with Uncle Sam, I've made a donation (I will be out of the USA through May 23 and I do NOT want to miss this opportunity!)
Fellow members, this is a once in a lifetime opportunity for you, and a chance to contribute to the opportunity for a young person wanting to embark on a pilot career. For me I'd add the Stinson to my Ford Trimotor (in AA color scheme) and a de Havilland DH-89 "Rapide" experiences.
Hint: Trimotors are excellent environments to wear your NR headsets or noise-blocking earbuds! (Unless you're up front wearing a Bose headset.) This ain't your newfangled pressurized, nicely lined and plush-seated aluminum flyin' sewerpipe.
