CAPE CANAVERAL, Florida, Nov 4: Hoping to cash in on a growing appetite for adventure, an Arizona startup has unveiled plans for a balloon ride to the stratosphere, offering passengers about two hours of space-like views from 19 miles above Earth. Privately owned World View, an offshoot of Paragon Space Development Corp., plans to start selling tickets at $75,000 per person within a few months, said Chairwoman and President Jane Poynter.
