As opposed to aircraft sitting on the tarmac, which are not subject to such problems?

Airplanes leak so much air that a couple more half-inch holes would not affect overall integrity. Most control systems are implemented with redundancy, so taking out a control point would just failover to a backup. Occupants aside, there little such damage could do to an airplane; noting the occupants, worst case is a couple casualties, not loss of everyone on board. And, of course, you could simply choose to not tak…

Aircraft are actually supposed to leak air. In non-bleedless aircraft, the engine compressors pressurize air to be used in the A/C unit, which then sends all the pressurized air throughout the cabin. To prevent excess pressure buildup, valves are opened partially most of the flight with a veinlike network of tubes venting air to the exterior of the aircraft.

Of course, if any damage occurred on the ground, this would be a non-issue entirely as the aircraft wouldn't be pressurized at all.

Are you? I wouldn't rule it out, but personally I think getting an outside signal into a sealed capsule which is moving so rapidly that it must use battery power rather than a physically connected power source seems more than trivial.

Nah, wifi would travel great in a long metal tube.

For 300 miles? Or are you proposing spacing hubs out along the journey, in which case, wouldn't frequent reconnection be an issue?

A dedicated hypoxia document by the FAA: http://www.google.be/url?sa=t&rct=j&q=&esrc=s&source=web&cd=... You got to think that a decompression will happen. Something traveling that fast inside a tube is probable to develope vibrations and material fatigue if something is not working properly (like the compressor or a air cushion), also there can be small parts released from the front pod impacting on the next one. It…

Obvious engineering issues for further investigation. I would just point out that fatal failure mechanisms can be pointed out in any transportation system. The acceptance criterion is a sufficiently low fatality rate.

Are you by any chance at the hyperloop team? I see that you only commented on this topic.
