First of all you need to go to forge and load up the forge world.

Go inside the hanger, and place a two way node teleporter, then go outside the hangar and look back at the door going to the hangar.

Under the door there is a sheet of glass, get another two way node teleporter and put it behind the glass.

Go back into the hangar and go through the first two way node teleporter.

To get out from behind the glass simply go back through the teleporter.
