Fantastic. I love some of those between-the-wars & pre-war aircraft, especially the Y1B-17 and P-12.

Nice Mark! 1 question, who the hell mounted a B-17 on top of the Empire State Building?

[Punisher05]

Niiiiiiiice Mark...you always impress with your finds

OK guys I have to show my ignorance for a second. What's the difference between the YB-17 and Model 299? Was 299 the initial prototype and the YB-17 the first production run?

The model 299 is Boeing's internal design number allocated to the entire B-17 family. The first (prototype) 299 was the (unofficial) 'XB-17' that first flew 28 July 1935 and was entered in the Air Corps' bomber competition. This aircraft crashed due to pilot error (elevator gust locks were not released). The YB-17 was a service test version of the original prototype. Thirteen of these were ordered, along with a 14th airframe for static testing. When one of the YB's was inadvertently spun after encountering violent weather, it became evident the airframe could handle extreme loads, so the 14th aircraft was completed as a flying article, and equipped with turbo-superchargers as the YB-17A. The famous high-altitude capability of the B-17 is founded on this aircraft's development. Sometimes the YB family is shown as 'Y1' due to the funding process for them which included so-called 'F-1" funds. Hope this helps.

Very cool! Thanks for clearing that up for me. And thanks again Mark for the link to the Model 299 shots, what a clean looking bird...
