This photo shows the 1958 Pacific National Exhibition (PNE) feature celebrating British Columbia’s centennial year.* Project X “was kept secret until the eve of the fair, when it was revealed that the attraction was a display of modern rocketry. The highlight of the show was a large standing rocket, complete with simulated blast off. Other displays included a Space Science club run by the Canadian Legion, a fifty-foot high American army missile, and earth satellites.” (Vancouver’s Fair. David Breen and Kenneth Coates. UBC Press: 1982, p.123).
*If CVA’s date for this image is accurate, it seems likely that the photo shows Project X being dismantled rather than constructed.
