1st floor, Langley hall, Wright brothers showed off their invention to the US Army, and a ton of Europeans...........one of them did, they seemed to separate a bit, Orville seemed to be the more competent brother, pictures of him in NYC harbor, with the Statue of Liberty in the background, showing the citizens of that area, New Jersey, to NYC...their invention, French, Spanish, Italians wanted to see their invention, they called it the "Wright Flyer"..

The user is likely thinking of Samuel Pierpont Langley and the Smithsonian Institution, which were involved in a significant controversy regarding the Wright Flyer and the claim to the first successful powered flight. There is no prominent individual named "Langley Hall Smith" associated with this history or the Italian Army. 

• Samuel Pierpont Langley was the Smithsonian's third Secretary and an aviation experimenter who attempted to build a man-carrying flying machine called the Aerodrome. His full-size machine failed to fly in late 1903, shortly before the Wright brothers' success at Kitty Hawk. The U.S. Army had provided a grant of $50,000 to fund his project.
• The Wright Flyer is the correct name of the aircraft that made the first successful flights at Kitty Hawk, North Carolina, on December 17, 1903, and it is on display at the National Air and Space Museum in Washington, D.C..
• A long-standing feud developed between the surviving Wright brother, Orville, and the Smithsonian because the Institution, for many years, displayed Langley's Aerodrome with a placard claiming it was "the first man-carrying aeroplane... capable of sustained free flight". Due to this, Orville sent the original 1903 Wright Flyer to the Science Museum in London in 1928, where it remained until the Smithsonian officially retracted its claims for Langley in 1942. The Flyer was returned to the U.S. and installed in the Smithsonian in 1948.
• The 1909 Wright Military Flyer was the world's first military airplane purchased by the U.S. Army Signal Corps, not the Italian Army. 

The name "Langley Hall Smith" appears to be a misremembered combination of Samuel Langley, the hall in the museum, and the general topic, and the "Italian Army" connection is likely a misattribution
