text: Late 20th century From the beginning, One Chase Manhattan Plaza had a 99% occupancy rate: the bank was on the lower stories, and 61 companies with a combined 2,500 workers were on the upper stories. The tenants were mainly financial tenants such as EF Hutton and Fuji Bank; law firms like Cravath, Swaine & Moore; and a private luncheon club called the Wall Street Club. The building's address caused problems for mail delivery persons and the general public. By the early 1970s, though the names of several other buildings in Manhattan ended in the word "Plaza", One Chase Manhattan Plaza was the only such building that did not have an address designation based on a surrounding street.  The "Group of Four Trees" sculpture in the plaza was installed in 1972.
  In its early years, the building faced several challenges. The glass panels began blowing away from the building during high winds: during 1962, fifteen glass panels fell from the building due to negative pressure caused by combination of the building's design and minute weaknesses in the glass. All of the building's 8,800 panels were reinspected, with similarly weakened panels replaced. A fire also took place in the sub-basement in 1962, and an anti-Vietnam War bombing occurred on the 16th floor in 1969, causing minor damage to the 16th floor. A Brink's truck in the building's underground garage was robbed in 1979 by two armed men driving a stolen fish truck, who took two hostages before transferring over $2 million into the refrigerated truck. The truck was later found abandoned, and the robbers escaped.
