Ethan Hunt begins the HALO jump in Mission: Impossible – Fallout at approximately 25,000 feet.
The sequence takes place during a mission over Paris, where Ethan and August Walker attempt to intercept a target. HALO means “high altitude, low opening”: the jump starts at high altitude, followed by a delayed parachute deployment that helps the team approach its destination covertly.
The production treated the scene as a major practical stunt. Tom Cruise performed the jump himself and completed repeated skydives while filmmakers developed specialized equipment for filming close-up footage in free fall. The sequence also includes a storm and a rescue effort that complicates the mission.
The altitude is often confused with the height of the later helicopter action or with ordinary skydiving altitudes. The film’s published descriptions generally identify the jump as beginning around 25,000 feet, making it a high-altitude military-style insertion.
