An airplane is a powered, fixed-wing aircraft that is propelled forward by thrust from a jet engine or propeller.
The Wright brothers invented and built the world's first successful biplane, when they made the first controlled, powered and sustained heavier-than-air human flight on December 17, 1903, four miles south of Kitty Hawk, North Carolina.
Emmett Brown was present during the first flight. He was caught on film, expressing his excitement on witnessing the event, as the airplane passed overhead.
Marty McFly, Jules Brown, and Verne Brown traveled from 1991 to August 5, 1926 in attempt to prevent an accident that caused Emmett Brown to have a fear of fishing. Instead, Emmett's line got tangled on a biplane flown by Roris Von Hinklehuffins. Emmett's stunt was recorded, and it caused him to become a silent film star when his Uncle Oliver signed a film contract with the director D.W. Tannen. After it became apparent that Tannen didn't care about Emmett's well-being, Oliver terminated Emmett's contract. Emmett's experience as a stuntman in his youth caused him to no longer have his fear as a grown man.
In the years following the first flight, commercial airlines became common. USAir was an airline that remained in operation in 2015 in the original timeline. They offered flights to Vietnam for surfers.
There was very nearly a midair collision when the hover-converted DeLorean time machine appeared slightly below the flight path of an airliner descending towards Hill Valley Airport when Doc, Marty, Jennifer and Einstein returned in the DeLorean time machine from 2015 to what was believed to be 1985, but was actually a nightmarish alternate reality.
