Jetscalator (1960)S
Reader Tom Z sent in this March 27, 1960 edition of Closer Than We Think, featuring the "Jetscalator." Tom explains:

This CTWT has held special significance for me (and anyone else who has used Dulles until quite recently). I haven’t flown in years, but I understand that the famous “Mobile Terminals” are finally gone, a case of a futuristic idea that didn’t work all that well in the real world.

The handful of times that I've been through the Dulles airport I've felt that I was going to miss my flight because of those slow moving shuttles. I hadn't heard that they might be doing away with the mobile lounges. Can anyone confirm that this is true?

The text from "Jetscalator" appears below:

Jet planes and the number of passengers they carry are getting bigger and bigger. Distances between terminals and loading docks are getting longer. The answer is a traveling waiting room with a moving ramp. Such a project is already being developed by the Chrysler Corporation, and it may be used at the new Washington, D.C., terminal now being designed by Eero Saarinen.

The "jetscalator," as it might be called, would move on wheels higher than a man.

It would have an up-or-down ramp and capacity for about 100 people. When departure time is at hand, travelers wouldn't have to stir from their chairs - they'd be transported in the "jetscalator" right to the side of the plane.
