The Fall of Skywatch

Skywatch investigates life signals coming from an asteroid drifing close to Earth. The astreroid is infested with aliens, who get aboard Skywatch and manage to slaughter much of the station's crew, and most of Stormwatch as well. Flint manages to escape, and brings help in the form of the WildC.A.T.s. they manage to rescue most of the stations survivors, except for Winter, who pilots Skywatch into the sun. Following this, Stormwatch is disbanded, as the Un is no longer willing to find the reconstruction of Skywatch again, nor raise and train a new team.
