and if we assume this is cylindrical then some problems present themselves. If you try to put two people next to each other, both are ducking the curvature of the wall to get into and out of their seats (assuming the wall is in place at the time). Also, on most long trips some type of bathroom facility is usually available. If you want to try and leave an isle to walk to and from a facility within the transport then having 2 people next to each other isn't a possibility.


The tube being evacuated also solves the sonic boom problem. There would be no buildup of air pressure on the front of the cylinder so there would be no boom.



I hate to think of what the TSA will put passengers through. An "Underwear Bomber" style attack on this thing, when traveling 700+ mph., would be a real mess.
