SEATTLE -- The Space Needle Foundation is offering the public the rare opportunity to walk the halo at the needle.

The Foundation estimates fewer than 100 people have walked the needle's 138 foot diameter halo, in the landmark's 54-year history. The top fundraisers of the upcoming Base 2 Space climb in support of Fred Hutch and cancer research will join that elite class of dare devils.

On Thursday, two KING 5 members, Jake Whittenberg and Danielle Leigh, we given the chance to walk the halo along with base jumper Luke Aikins to raise awareness about the upcoming event.

Greg Copeland also climbed the 90 flights and 832 stairs from the base of the needle to the observation deck along with several other runners to help the needle prepare for the October climb.

Sunday, October 2, will mark the second time in Space Needle history people have been allowed to climb the open-air stairs.

"It's important for the Space Needle to not only be a landmark for the city but to also be invested in the community," said Dave Mandapat, director of Public Relations.

"We wanted to do something deliberate that activated our structure to help fund a local organization's efforts to support cancer research which impacts all of us."
