The street view of a parade held for Howard Hughes in Chicago. Hughes can be seen sitting in the first black car in line, wearing a white outfit as he waves to the surrounding crowd.
Transcribed from attached press release: "HUGHES READY FOR TAKE-OFF IN SECOND XF-11 FLIGHT. CULVER CITY, Calif., April 5. Howard Hughes, famed flier-industrialist, recovered from injuries following crash last July 7, is shown here just before he test-piloted today a duplicate of the plane in which he nearly lost his life. He designed and built the plane, designated XF-11, and one of the world's fastest photo-reconnaissance ships, for the Army Air Forces in conjunction with the Air Materiel Command engineers."
Howard Hughes is sitting on the ground examining an architectural drawing of the Hughes Culver City plant. There is a section on "Intake Duct Body Plan."
