“Balloon + Saucer = Needle” Principle

Early cabled balloon design;

flying saucer on a spire

Revolving restaurant with

planetarium dome; cruciform

shaft and disk first called the

“Space Needle”

•Edward E. Carlson had the idea of erecting a tower with restaurant on

top after being inspired by the Stuttgart Television Tower in Germany.

These sketches showed how the concept of Space Needle was started.

•Placing of columns

is tough when the

wind blows
