The Space Needle was built in 1962 for the World's Fair
Top of the Space Needle - Aircraft Warning Beacon: 605 feet
Observation Deck: 520 feet
The Space Needle is approximately 1,320 Milky Way candy bars (605 feet) tall.
The Space Needle is fastened to its foundation with 72 bolts, each 30 feet in length.
On a hot day the Space Needle expands about one inch.
During the construction of the Space Needle, it took 467 cement trucks less than 12 hours to fill the foundation hole (30-feet deep and 120-feet across); this was the largest continuous concrete pour ever attempted in the West.
As an April Fool's joke a local television station aired a phony report that the Space Needle had fallen over. Emergency phone lines were swamped with calls. The Space Needle received more than 700 calls, even though there was a flashing alert during the entire report telling the audience that it was a joke. One Spokane man even jumped in his car and began driving to Seattle because his daughter worked at the Space Needle.
