Fitzwire--Today at Sun Link Mission Control, in Houston, Texas, the countdown for the launch of the modern streetcar began at 12:05 P.M., Mountain Standard Time. Powered by electricity and Rice-A-Roni, the San Francisco treat, Tucson’s modern streetcar will liftoff at 9 A.M. on Friday if no glitches delay the much anticipated launch. The excitement is palpable among the flight engineers and all associated with the inaugural flight of the streetcar which if all goes according to plan should orbit the urban core of Tucson for decades.
