The '''Black Mesa Air Control''' is a topside area of the Black Mesa Research Facility covered during the ''Half-Life Decay'' chapter ''Half-Life Decay storyline Green|Code Green''.

==Overview==

The Air Control building is adjacent to a large airstrip, and is used to monitor and direct activity in the airspace above Black Mesa. Special clearance codes have to be entered at this building before any rocket launch can take place in any other area.

==Behind the scenes==

As seen in an early ''Decay'' screenshot, the players were to enter the blue hangar in front of which the HECU soldiers are offloaded by an Osprey. There a dismantled Osprey was to be found. What remains is only the small door to enter it, while its inside was completely removed.
