Toward the Unknown 1956

USAF Major Lincoln Bond [William Holden] endures 14 months of torture during the Korean War, eventually signing a confession that is used for propaganda. After his release, he spends a year slowly rebuilding and then returns to Edwards Air Force Base, hoping to resume his career as a test pilot. On his arrival, a plane crash lands on the dry lake bed nearby, and he races toward the flames, risking his life to pry the canopy free and save the pilot.

His brave rescue is witnessed by his old comrade Col. ‘Mickey’ McKee [Charles McGraw], but base commander Brigadier General Banner [Lloyd Nolan] remains wary, doubting Bond’s stability and suitability for flight duty. Complicating matters, Banner’s secretary and old flame, Connie Mitchell [Virginia Leith], harbors conflicted feelings toward him.

Bond is eager to return to work and accepts Banner’s offer of routine flying in support. Banner, a hands-on leader, insists on taking the most dangerous assignments himself, setting a high bar for Bond’s rehabilitation and acceptance within the unit.

When Bond flies the Gilbert XF-120, he uncovers dangerous structural problems that could derail the fighter’s acceptance. He maintains he did not push the aircraft beyond its design limits, but skepticism persists from H. G. Gilbert’s side of the project and from Harvey Gilbert [Ralph Moody]. When Banner attempts to duplicate Bond’s maneuvers, nothing goes wrong, though Bond notices Banner nearly collapse in the locker room, a telling sign of the general’s fragility.

Bond’s recovery is further threatened when Maj. Bromo Lee [Murray Hamilton], Banner’s top test pilot, is hammered by drink and aggression at the officers club, leading Bond to respond with a measured restraint that echoes his wartime ordeal. The tension peaks when close friend Lt. Col. Joe Craven [James Garner] is killed when a wing of the XF-120 tears away, validating Bond’s warnings about the aircraft’s danger.

With both pilots accountable, Banner opts for mercy rather than punishment and assigns Bond to the rocket-powered X-2 program—the project Bond has pursued for years. Yet Banner insists on piloting the first full-power test himself, despite pressure from higher-ups who would rather see a younger pilot take the risk. Bond is later ordered to fly the last half-power test, but he pushes to full power without explicit authorization and survives a perilous high-altitude bailout. The base flight surgeon tells Banner that only a young, fit person could have endured such a test, prompting Banner to accept a promotion and transfer and to cover Bond’s actions by claiming he had given verbal authorization to go full power if necessary. Banner then recommends Col. McKee as his successor.

Before leaving, Banner offers to take Connie with him, but she decides to stay with Bond.
