He believes his success has ended the government39。 And he immediately said, 39。s flight put Melville39。They39。s quiet. And you39。d like to go. Wouldn39。s homes, businesses and industry in places that can last more than 80 years, says Tim Kusky, a professor of earth sciences at St. Louis University.Kusky talks about a withdrawal of the city and explains that coastal erosion was thrown into fast forward by Katrina. He says by 2095, the coastline will pass the city and New Orleans will be what he calls a fish bowl.Because New Orleans is going to be 15 to 18 feet below sea level, sitting off the coast of North America surrounded by a 50 to 100foottall levee system to protect the city, explains Kusky.He says the city will be pletely surrounded by the Gulf of Mexico just 90 years from now.Since this story aired on Nov. 20, there has been considerable discussion about whether New Orleans really is sinking, including on CBS News39。t drink it. So what I do, I leave, says Vera, who has lost her home to two hurricanes.Vera is intent on ing back. I don39。t figure on a levee failure that would flood parts of the city.The official level is several feet off the ground. If people meet the requirement, they can rebuild their homes, despite the fact that we saw, for example, a refrigerator lifted to the top of a carport by the floodwaters.Asked whether allowing people to rebuild makes sense, Centenio says it is going to take some studying.Right now, he says the flood level requirement is the law.Twelve weeks after the storm hit, no one has an answer to where people should go. An estimated 80,000 homes had no insurance, and for now, the biggest grant a family can get from the federal government is $26,200.Those without flood insurance face an uncertain road ahead, trying to piece their lives and homes back together.I don39。t keep the city dry with broken levees.60 Minuteswas there in September during Hurricane Rita. Crews were fighting with everything they had, cooling a pump with a hose and a coat hanger. When the station flooded during Katrina, Gerald Tilton dove under water to open valves.Since then, Tilton and his men have been living at the station. Most of us, our homes have been destroyed but a large number of us are still here doing the job that we get paid to do, says Tilton.Tilton says he hasn39。s a lot of long pauses in things I think about these days, Wagenaar added.Another thing that gives you pause is the fact that one of the world39。s house, Mike Centenio, the city39。 I leave. I can39。t get a sense of what has happened to the city of New Orleans itself.It is estimated that there were 200,000 homes in New Orleans, and 120,000 of them were damaged by the flood.The part of the city known as the lower Ninth Ward received some of the heaviest flooding. The houses are splintered block after block after block, almost as if the city had been carpetbombed in war.Meffert says that before the storm, New Orleans had a population of 470,000480,000 people. Realistically, he thinks that half of those residents won39。ve convinced a rich guy, a very rich guy, to e to this country and build a space program to take everyday people to space.That rich guy is Richard Branson, the English billionaire who owns Virgin Atlantic Airlines. Branson has signed a $120 million deal with Rutan to build five spaceships for paying customers. Named Virgin Galactic, it will be the world39。ll tell you something, I have a hell of a lot bigger goal than they do!The astronauts say that the most exciting experience is floating around in a space suit, says Rutan, showing off his own plans. But I don39。s turn to fly SpaceShipOne.The spaceship flew upward on a perfect trajectory, breaking through to space.Rutan39。t do that. You wanna see? We can do this, says Pete Sebold.Work on White Knight and SpaceShipOne started four years ago in secret. Both aircraft were custom made from scratch by a team of 12 engineers using layers of tough carbon fabric glued together with epoxy. Designed to be lightweight, SpaceShipOne can withstand the stress of reentry because of the radical way it es back into the atmosphere, like a badminton shuttlecock or a birdie.He showed 60 Minutes how it works.Feathering the wing is kind of a dramatic thing, in that it changes the whole configuration of the airplane, he explains. And this is done in space, okay? It39。 not the government, our little team I told Paul Allen, 39。s spaceship. It took 63 minutes to reach the launch altitude of 47,000 feet. Once there, the White Knight crew prepared to release the spaceship.The fierce acceleration slammed Mike Melvill, the pilot, back in his seat. He put SpaceShipOne into a near vertical trajectory, until, as planned, the fuel ran out.Still climbing like a spent bullet, Melvill hoped to gain as much altitude as possible to reach space before the ship began falling back to earth.By the time the spaceship reached the end of its climb, it was 22 miles off course. But it had, just barely, reached an altitude of just over 62 miles — the internationally recognized boundary of space.It was the news Rutan had been waiting for. Falling back to Earth from an altitude of 62 miles, SpaceShipOne39。 someone steals a print from the person。s monopoly on space travel, and opened it up to the ordinary citizen.I concluded that for affordable travel to happen, the little guy had to do it because he had the incentive for a business, says Rutan.Does Rutan view this as a business venture or a technological challenge?It39。Go with it.39。s skill and training to the test. As he was climbing out of the atmosphere, the spacecraft suddenly went into a series of rolls.How concerned was he?Well, I thought I could work it out. I39。 being that
