The Lockheed Orion Model 9 was a single engine passenger aircraft built in 1931 for commercial airlines. It was the first airliner to have retractable landing gear and was faster than any military aircraft of that time. It was the last wooden monoplane design produced by the Lockheed Aircraft Corporation. It was designed and built by Richard A. Von Hake, but an interesting historical note is that Kelly Johnson of SR-71 fame was flight test engineer on the project. #9 #Aircraft #Airplane #Commercial #Engine #Lockheed #Model #Monoplane #Orion #Plane #Single
