Cylons. The Carrier was following the fleet in several FTL jumps but was lost on the 238th jump. The fleet had no idea that the Carrier was missing until the ships began to report in. The Galactica figured out that the ship was missing when it didn't show up on radar. The other ships just moved on including Galactica. Then later out of the blue the Olympic carrier showed up on a course to rejoin the fleet. The Galactica sent 2 Viper fighters and a Raptor to intercept the ship. The 3 fighters contacted the Carrier and the captain said to the three fighters "We got lost and we used the three hours we had to repair the malfunctioning FTL drive." and the fighters terminated the communications with the Carrier and then the Galactica's crew detected the presence of a nuclear warhead on board the ship and orderd the fighters to keep communications offline with the ship and instead flashed the message "Stop your engines and stay away from the fleet" but the ship still had the engines at full. The fighters sent a message to the ship Colonial One and the president on board told the fighters to destroy the Carrier if it posed any threat to the fleet. The fighters continued to send messages to the ship to stop its engines but got no response. With the ship looming closer to the fleet, one Viper fighter codename "Apollo" went along the starboard side, then approached the ship's stern and aimed the fighter's guns directly at the Carrier's engines and, hesitating, opened fire. The Olympic Carrier shuddered from the impact and exploded in a chain reaction. With nothing left from the explosion or debris, that ended the Olympic Carrier.
