The speed of the Aeros is in the same league as a good bullet train, which may be attractive to a lot of travellers. I prefer trains to planes (even the old-fashioned American kind), when I'm not in a big hurry. The pace is leisurely and unhurried, and the accommodations are roomy--an ordinary Amtrak seat is as big as first-class on Lufthansa. Even better is the ability to get up and stroll around without a flight attendant scowling at you for blocking the drink cart...as you walk down to the bar car to get your own damn drink, thank you very much. Amtrak doesn't seem to have full dining cars like the old days, but the snack car is decent enough, and better than airline food.

You don't have the choice of a train crossing the Atlantic, it's either a slow boat or a fast plane. I think the Aeros would fit nicely into that unoccupied "ecological niche" of medium-speed travel.

I think the only thing better than train travel would be dirigible travel aboard something like the Aeros. All the comforts, and you're floating 8,000 feet above the scenery. Could there be a classier way to travel? (On Earth, anyway...)
