The Space_Needle became an instant Seattle landmark since the early 1960s. The same for the Calgary_Tower by the late 1960s.

Both were possible, because Seattle & Calgary aren't under anything like Vancouver's imposed restrictions.
The H._R._MacMillan_Space_Centre opened in October 1968, some 4 months after the Calgary Tower & 6.5 years after the Space Needle. Of course Vancouver was behind, as usual. The first thing that you notice is that there is no tower. It's a classic stump of a building.

The movie Final_Destination_Bloodlines provides a CGI depiction of what an actual tower, not a stump would look like. https://en.wikipedia.org/wiki/Final_Destination_Bloodlines#Plot
While Final_Destination_Bloodlines was filmed in Vancouver, it was set in New York State.
Something peculiar happened in Seattle in 2025.
