With Marvin's aid, McClane reaches the aircraft before Stuart's henchmen, but Stuart traps him and throws grenades into the cockpit. McClane escapes via the ejection seat as the aircraft explodes. Barnes helps McClane locate the mercenaries's hideout and they tell Grant and his team to raid the location, but the mercenaries escape on snowmobiles. McClane pursues them, but the gun he picked up does not kill anyone when fired. He discovers that the gun is loaded with blanks, and concludes that the mercenaries and Special Forces have been working together all along.
