Speed (1994), "Bus versus plane"
After toughing it out on a bus that can't go below 50 miles per hour, Sandra Bullock and Keanu Reeves narrowly escape their runaway transport before it smashes into a cargo plane at LAX and goes up in flames. Astute viewers may notice that behind the action are a number of unusual background mountains. This particular explosion was not filmed at LAX, special effects coordinator John Frazier (who would later help Michael Bay create his much lauded "Bayhem" on films like Armageddon and Transformers) opting to film the dangerous stunt at a desert runway at Mojave Airport using a decommissioned cargo plane (reportedly costing $80,000).
As well as the voluminous fireballs crafted by Frazier's team, the explosion featured several in-jokes. The plane's logo displays 'Pacific Courier Freight', a gag from Speed production designer Jackson De Govia, who had used that same name on a truck in Die Hard and Die Hard: With a Vengeance. Following the blast, the driver of the vehicle towing the plane makes a run for it -- that's the film's line producer Ian Bryce.
Back in the day, if you caught Speed on a plane, you missed this massive moment. Possibly to calm any nervous flyers, the 'airline version' of the film removes the actual bus-hitting-plane crash and shows only the reaction of the now-safe bus passengers to a non-existent explosion.
