Launch Bay 7

Launch Bay 7 was a part of the UNSC Halcyon-Class Cruiser Pillar of Autumn. It held a single Longsword-class Interceptor/Fighter, which was used by the Master Chief and Cortana to escape from Alpha Halo. It also has enough storage capacity for sixteen Pelican dropships and a large number of Scorpions and Warthogs.

This Hangar bay can be seen in the last cutscene on the Level "The Maw", but might be also the one seen at the beginning of the Level "Pillar of Autumn".
