Andy explained how the double-strength duralumin had increased the strength of the frame to such a point that a disaster such as had befallen the Shenandoah could not strike the Goliath.

“How many passengers will you be able to carry when the ship goes into transcontinental service?” Harry asked.

“We’ll have sleeping accommodations for 200,” replied Andy, “and during daytime runs between large cities will be able to carry an extra 100.”

“Will the fares be pretty stiff?” asked Harry. “Not as much as you would expect. They will average railroad plus Pullman.”

“In that case,” said Harry, “you can be sure of capacity business for a good many years.”

“We’ll have to if National Airways is to break even on the operation of the Goliath,” said Andy.

Bert, who had remained in the office to check over blueprints on an especially complicated piece of radio equipment for the Goliath, hurried up.

“Andy,” he said. “Herman Blatz is here.”

“Who?” asked Andy.

“Blatz,” repeated Bert, “Herman Blatz. He’s the civilian observer from Friedrichshafen.”
