A mid-air collision leaves a 747 without a pilot. Charlton Heston, Karen Black and George Kennedy star in this campy far fetched adventure. Acting is wooden and unconvincing and the plot ranges from strange to absurd but the air sequences are by far the best in any air disaster film and well worth a look. It is a typical disaster film for it's time but is thankfully one of the good ones unlike The Concorde or The Swarm. People give it a hard time claiming it to be one of the worst films ever made but it obviously isn't as there are many millions of mainstream films worse than this and many worse disaster movies if you want proof watch any of Irwin Allen's late 70's productions.
