Elon Musk Says He Has 'Verbal' OK To Build N.Y.-D.C. Hyperloop
A plan to build an ultrafast Hyperloop tube train has been given "verbal [government] approval" to connect large cities on the East Coast, tech entrepreneur Elon Musk says. He adds that the system would whisk passengers from New York to Washington, D.C., in 29 minutes.
Any idea on how this would affect airlines and Amtrak?
