Permanent Link to ‘Mission Impossible – Fallout’ includes helicopter stunts with NovAtel onboard
Screenshot: Paramount Pictures
A NovAtel GNSS antenna guided Tom Cruise as he performed stunt helicopter dives for his latest movie, “Mission: Impossible – Fallout.”
A LinkedIn post from the company suggests theater-goers “Keep an eye on the scene where Tom Cruise flies a helicopter through a narrow canyon to catch our Compact GNSS Antenna in action!”
Above is a behind-the-scenes video that shows how Airbus helped Cruise, an actor known for doing many of his own stunts, learn to fly a helicopter and navigate a treacherous dive sequence (with the aid of the NovAtel receiver).
