It then uses its telepathic powers to immobilize the President and fling him to the ground. The military personnel with the President then shoot the alien through the glass, with Major Mitchell stepping through the broken glass and delivering a final head shot.
During the instant that President Whitmore was immobilized, he said he was sharing the thoughts of the alien. He learned that the aliens have done this before.
They attack planets, use up the resources, kill the life forms, then move on. President Whitmore now issues very clear orders to "nuke the bastards." B-2 Spirit bombers are deployed, with the first destroyer targeted one that is hovering over a deserted Houston, TX.
That weapon explodes, but proves ineffective at penetrating the craft's force field and destroys the city instead; as a result, the President orders the remaining bombers called back.
President Whitmore and his daughter are reunited with the First Lady, Marilyn Whitmore at Area 51. Mrs. Whitmore had been on a working trip to Los Angeles and got caught up in the destroyer attack there. Captain Hiller's exotic dancer girlfriend, Jasmine, rescues the First Lady when she comes across the wreckage of the helicopter the First Lady had been attempting to escape in.
Captain Hiller later locates Jasmin, her son Dillon, and the First Lady camped out in the remains of El Toro MCAS and flew them in a helicopter to Area 51.
A doctor tells the President that his wife has uncontrollable internal bleeding. When the President goes in to see her, he says, "The doctors say you're gonna be just fine." She smiles and responds softly, "Liar." She dies not long after that.
On July 4, President Whitmores nerves are understandably frayed, so when Secretary of Defense Nimzicki again barks at him about his decisions and actions, President Whitmore physically pushes him and fires him on the spot.
David Levinson suggests a plan that involves using the newly operable attacker to gain access to the interior of the alien mothership in space in order to introduce a computer virus that will disable the protective shields around the destroyers and attackers.
Once the computer virus took effect, nuclear weapons would be used to destroy the mothership. Hiller volunteers to be pilot the attacker, with Levinson accompanying him to upload the virus.
With satellite communications knocked out, the Americans have used Morse code to coordinate an attack with the remaining forces around the world, timed to occur when the invaders' shields are set to fail.
With not enough military pilots to man all available aircraft, the battle requires several volunteers, including President Whitmore and Russell, who both have previous combat flight experience.
Hiller and Levinson successfully reach the mothership and implant the virus. President Whitmore leads the American jet fighters against the alien destroyer that is approaching Area 51.
Although the aliens now lack shields, the fighters' supply of missiles are quickly exhausted against the colossal craft and its large complement of assault ships.
The underside of the alien craft opens up as its directed energy weapon prepares to fire on the base. Russell possesses the last remaining missile, but his firing mechanism jams; he decides to pilot his aircraft into the alien weapon in a kamikaze attack.
The explosion causes a chain reaction which annihilates the ship. Human resistance forces around the world use the same weak point to destroy the remainder of the alien ships, while the nuclear device planted by Hiller and Levinson destroys the alien mothership soon after the duo escape.
Hiller and Levinson are caught up in the aftereffects of the mothership's explosion, but are able to return to earth unharmed, crash-landing the alien fighter in the desert close to Area 51.
Dry Lake Dessert, minutes later: Several army jeeps race across the arid desert floor. As they whip past we see they are headed towards a gigantic black plume of smoke in the distance. The Jeeps skids to a halt. Jasmine and Constance are the first to leap off the Jeeps.
Steve and David walk towards us, cigars in their mouths. Jasmine races over to him. Constance comes running up to David, hugs him tightly. Behind them Dylan, Patricia, the President and General Grey come walking over. The President and General Grey approach. As they begin to celebrate, they look up to the sky.
Brilliant lights in the skies. The debris from the Mother Ship explosion enters the atmosphere like thousands of shooting stars. It's an incredible sight. The group stares happily at the show in the sky. Steve takes Dylan by the hand. Everyone stares in wonder at the beautiful lights.
