The Hangars: The Base also housed the flying machines made from the projects Vril and Haunebu. Huge hangars were prepared to accommodate and maintain the machines.

All of them, except one Haunebu model III, left the installation in order to establish more secure bases, first on the dark side of the Moon and finally on Mars. One of the engines of the remaining aircraft was removed and used to build part of the inter-dimensional portal, leaving the machine anchored to the ground.
