Weld Professor of Atmospheric Chemistry James Anderson, who has been working on the project since last year, said he thinks successful operation of the plane will measurably speed atmospheric research and enable scientists to better determine options for controlling ozone depletion...
Anderson and the plane's architect, John Landford, who is the president of Aurora Flight Sciences, said they hope to send the plane through the ozone layer in August...
...plane, called the "Perseus," is expected to give University researchers new information on the ozone depletion level and its correlation to such things as climate changes and global warming...
...Perseus" is an innovative device in atmospheric research efforts because it is light and will travel as high as 85,000 feet in the stratosphere, whereas manned planes are not able to go beyond 68,000 feet. The plane is also considered more efficient for the project because it can travel for longer periods than piloted planes...
