Transcribed from press release attached to back of photo: "NEW-DESIGN PHOTO PLANE COMPLETED CULVER CITY, Calif., July 7 -- test-flown today for the first time, the new XF-11 was revealed as one of the world's fastest long-range photographic planes. It was designed and built by Howard Hughes in conjunction with the Air Materiel command engineers. Army officials said that it can attain a speed of more than 400 miles per hour and a ceiling of more than 40,000 feet. The plane has a pressurized cabin making it unnecessary for the crew to use oxygen masks. Outstanding features include a full-span flap, unique eight-camera layout and exceptionally fast take-off." Transcribed from photo sleeve: "Howard Hughes sits in the cockpit of the XF-11, a reconnaissance plane that Hughes built and designed in conjunction with Air Materiel Command engineers.
