Howard Hughes sitting inside the Lockheed 14 aircraft in New York. Typed on a piece of paper attached to the image: "Hughes' Paris hop delayed by motor trouble. New York City-- Howard Hughes, millionaire oil man and speed flyer, in the cabin of his huge Lockheed plane as he waited impatiently for a crew of mechanics to repair one of the motors so that he could take off for Paris. He was forced to give up his plans to leave on July 9th when mechanics found that it would be impossible to change the 18 cylinders of his motors in time. Crews worked all night at the job. Rough spots were found in the cylinders during fuel consumption tests. Credit Line (ACME) 7/10/38 Burs SF."

Typed onto a piece of paper attached to the image: "New York hails heroes of World Flight, New York City --- In the greatest reception since Lindbergh's, Howard Hughes and his gallant companions paraded up Broadway today, almost smothered beneath New York's ticker-tape accolade recognizing their record-smashing world dash. Here's Hughes, (center back, seat), gazing up the tons of torn paper fluttering down on him and his comrades, following in the car behind. Beside Hughes on the left is Grover Whalen, head of the New York World's Fair, 1939. Credit Line (ACME) 7/15/38."
