Boarding Tube

The boarding tube is a short corridor, either 4foot or 8foot long, which connects the travel tube to an Eagle or other spaceship. The interior panels are identical to the airlock interior. The interior set does not resemble the extending boarding tube seen on the Launch Pad exterior.

Black Sun
The exterior- a much longer boarding tube.
Breakaway
The travel tube single door connects to the boarding tube.
Black Sun
View to the Eagle door.
Collision Course
The reverse view, to the Travel Tube door. Note the standard signage, although the horizontal panels around the door are unique.
War Games
A longer design, blown open to space.
Space Brain
The travel tube door here is a standard door with minimal signage.
Seed Of Destruction
Back to the first door with additional signage.
Dragon's Domain
In Dragon's Domain, there is no travel tube- just a long Moonbase corridor (longer than the launch pad buildings on the exterior views). The "No Access" and "Count Down" signs are unique to this "Embarkation Point"
The Testament Of Arkadia
In Testament Of Arkadia, there's no door to the corridor behind.
Dorzak
The red atmosphere seal. Although normally it wraps over the sill over the Eagle door, it can adapt to vertical spaceships hulls.
Dorzak
Although the panels are normally red, in some episodes such as Breakaway and here in Dorzak, they are white. While there were two panels forming an 8-foot corridor in Year 1, there was just one 4-foot wide panel in Year 2.
The Testament Of Arkadia
Where are these lateral doors on the interior set?
Space Warp
Space Warp: this is the only time an area on the launch pad is seen. Two different travel tubes ("1" and "2b") terminate at this room.
Space Warp
Space Warp: the angled door marked "Eagle Four Boarding Tube" is behind the space animal. It is the same design as the internal Eagle doors, and the exterior travel tube door.
Space Warp
Space Warp: this area overlooking the Eagle hangar is adjacent to the previous reception area. The panel behind Helena is the Convertor Main Unit panel as seen in the Main Power Unit in Earthbound (the "Do Not Open" sign is visible, but the big "Danger" sign is not).
Space Warp
The boarding tube is above ground, and the hangar is below ground, yet we see the hangar roof from the window.
Space Warp
Note the Command Center desk.
Space Warp
Returning through the reception area.
