"a crew of 155": he found it easier to shed some assumptions than others.

dearieme -- And it would have been helpful if he'd mention what all those folks would actually do.

Given a nearly two-day flight time for Chicago-England, perhaps he used ration of ocean liner crews to passengers and then scaled that down a bit. Must have figured the plane would be equivalent to a speedier liner.

Bel Geddes forgot that airplanes are assembled in factories. The broadest clear span of a truss-roof building has remained 250' for the past seventy years, and that is why aircraft have almost never had wingspans greater than 240 feet. Roofing a factory floor broader than 250 feet takes construction techniques more appropriate to bridge-building, and typically twice as much steel girder, unless one goes to cable stays, which opens a whole new can of worms. At any rate, airport designers count on a wingspan less than 250 feet. Nowadays an airliner with a wider wingspan could not dock with the boarding ramps jutting from the sides of airport arrival buildings, but force the passengers to deplane onto the apron and take buses to the arrival building.
