In 1958, two U.S. Air Force pilots and aspiring astronauts, William "Hawk" Hawkins (Tommy Lee Jones) and Frank Corvin (Clint Eastwood), are testing a modified Bell X-2 when Hawk decides to break a height record. The plane stalls and they are forced to eject, narrowly missing a Boeing B-50 Superfortress flying with navigator "Tank" Sullivan (James Garner). On the ground, Frank punches Hawk, but their fight is broken up by flight engineer Jerry O'Neill (Donald Sutherland). Their boss, Bob Gerson (James Cromwell), chastises Hawk, before taking them to a press conference, where he announces that the newly created NASA, rather than the USAF, will be conducting space flight tests.
