Air racers...

Saw this poster on a blog (http://progress-is-fine.blogspot.com):

It reminded me of a section of Oshkosh air museum (Oshkosh by Gosh...8/30/15) that was dedicated to air racers and stunt planes. Apparently the air races were as popular in the 1920's and 30's as Nascar or the NFL is today. Here's a few photo's from the air museum's collection:

The Laird Super Solution was an air racing champ in the early 30's, flown by Jimmy Doolittle. It's kind of surprising that they were still using biplanes for racing by then.

The Stearman Model 75 was a WWII trainer modified after the war as a stunt plane. It was given a more powerful engine and dubbed "Super Stearman" (photos courtesy of the Oshkosh EAA Air Venture Museum).
