The Skyview Tower.

The Sky View Tower was a 494ft tall skyscraper with its restaurant the Sky View that opened and closed in 1969. Although extremely ritzy and coveted, the tower saw a rushed construction, being opened five months ahead of schedule with poor operational standards. Though these flaws could've led to a total collapse and the deaths of all guests during its opening day, such a disaster was entirely prevented by Iris Campbell warning patrons of the impending danger. The tower was closed for inspection and renovations, but never reopened before being demolished. Timeline: 1968 V3.
