has anyone suggested to Musk that he could make a fortune on a gigantic seaplane made out of, say, spruce

@dfeldman I used to make fun of the Spruce Goose... until I saw it in person in that air and space museum in McMinnville, Oregon

And utterly fell in love with it. It's the most beautiful plane I have ever seen.
