The "hanger" is a Decepticon operations center in the cartoon portion of the Generation One continuity family.

The "hanger" (marked as such in white letters) was located on the grounds of an airport. It was used by the Decepticons as a hideout while trying to destroy plans for a new drone-fighter from EJK Laboratories. Bumblebee, while picking up Sparkplug Witwicky at the same airport, discovered the Decepticons, and sent a message to Prime, who dispatched the Dinobots to deal with the Decepticons. A missile drop from Swoop caused Thundercracker and Thrust to crash into the hanger.

It blowed up real good. Desertion of the Dinobots, Part 1
