Operation British

During the One Week Battle of the One Year War, the Zeon Armed Forces moved a depopulated colony off of Side 2 to try to attack the Federation base at Jaburo which had withstood all attacks, even those of nuclear weapons. The Federation managed to divert the colony from Jaburo, but it still plunged to Earth.

What it hit was Sydney, Australia. Unlike the Colony Drop of Dublin nearly ten years later, when the colony impacted the earth it exploded, causing a massive crater.
