FAA clears way for Space Elevator testing.

The LiftPort Group, the space elevator companies, announced September 9 that it has received a waiver from the Federal Aviation Administration (FAA) to use airspace to conduct preliminary tests of its high altitude robotic "lifters."

The lifters are early prototypes of the technology that the company is developing for use in its commercial space elevator to ferry cargo back and forth into space.

The tests, which are planned for early fall, will simulate a working space elevator by launching a model elevator "ribbon" attached to moored balloon initially up to a mile high. The robotic lifters will then be tested in their ability to climb up and down the free-hanging ribbon, marking the first-ever test of this technology in the development of the space elevator concept.

According to Michael Laine, president of the LiftPort Group in Bremerton, Washington, the FAA go-ahead is a "critical step" in the ultimate developing of the group's LiftPort Space Elevator concept.
