Your job is to generate a story 100 to 1000 words long, that includes all the facts given as input in their order of appearance while expanding upon them to produce a broader, yet coherent, narrative.
Input: Fact1: small crew led by Commander Harold Roberts and reporter are on expedition into Antarctica for United States Navy, Fact2: Roberts are called to ship, Fact3: rotor breaks and unable to stay in air they start to descend, Fact4: Hunter has learned to survive in land, Fact5: ship have to leave before Antarctic winter sets

A small crew led by Commander Harold Roberts and reporter Maggie Hathaway are on an expedition into Antarctica for the United States Navy. During a helicopter flight, they are called back to their ship via radio because of an unexpected storm approaching. At first they try to fly around the storm, but low on fuel, they fly into the storm, where they almost collide in midair with a mansized pterosaur. Their rotor breaks and unable to stay in the air they start to descend, and are surprised when they end up landing well below sealevel in a warm volcanic crater. Inside, they discover a steamy tropical jungle populated by living dinosaurs, giant flesheating plants, and fresh human footprints. The crew encounter many dangers and perils in the jungle in a fight for survival. The crew meet Hunter, the lone survivor of a plane crash from the 1947 expedition. He has learned to survive in this land with the aid of a conch that drives off the animals and by raiding the dinosaurs nests. He offers the remains of his airplane to repair the helicopter, but only if the crew agree to leave Maggie with him. The crew refuses, but they also know that after 25 days their ship will have to leave before the Antarctic winter sets in. Unsuccessful in finding the remains of the plane, hidden by Hunter, the crew debate leaving Maggie, or forcing the information out of Hunter by torture. Commander Roberts refuses to sink to either low. Maggie is later attacked by an Elasmosaurus, but Hunter rescues her. After a fight and learning that the crew refuse to torture him for the location of the plane, Hunter gives them the map to its location. After repairing the helicopter, the crew take off in a hurry as a Tyrannosaurus Rex attacks their base. They fly to pick up Maggie, who is with Hunter at the time. Hunter is ambushed by the Elasmosaurus, and the crew come to his rescue. They fly out of the lost world with him. Once clear of the crater, the crew are able to communicate again by radio with their ship; however, the helicopter runs out of fuel and crashes into the ocean before it reaches the vessel. The crew are rescued, and once safely on the ship Harold and Maggie declare their love for one another. The animals featured in this film include a Tyrannosaurus, Elasmosaurus, Stegosaurus live acted by monitor lizards which would technically make them Megalania, a pair of Pterosaurs and a giant fleshconsuming plant. The mammal found by the crew then later eaten by the carnivorous plant is referred to as a tarsier but is actually a loris.
