"the mathematician and a pilot delivered the virus and nuke to the mothership."

Go watch the movie again.

http://en.wikipedia.org/wiki/Independence_Day_(film)

On July 4, David devises a plan to use the repaired attacker to gain access to the interior of the mothership in order to introduce a computer virus and plant a nuclear bomb. It is hoped that this will cause the shields of the Earth-based alien craft to fail long enough for a worldwide attack to eliminate them. Hiller volunteers to be the mission's pilot, with David accompanying him to upload the virus. With few pilots to man available aircraft, the battle requires volunteers, including Whitmore and Casse, who have previous combat flight experience. Morse code is used to contact forces around the world in order to coordinate the attack.

After the virus is implanted and lowers the shields, Whitmore leads an attack against a destroyer approaching Area 51. The fighters' supply of missiles are exhausted against the craft and its large complement of attackers, and the destroyer prepares to fire its main weapon at the base. Casse possesses the last remaining missile, but his firing mechanism jams. He pilots his aircraft into the center of the alien weapon in a suicide attack, annihilating the ship. Using this method, other forces around the world are able to destroy the remaining destroyers. David and Hiller escape the mothership just as it is destroyed by the nuclear bomb, and the duo crash land near Area 51. The world celebrates, and the main characters watch debris from the mothership enter the atmosphere.
