On June 16, 1969, Sun Realty filed a claim against Plaza Tower, Inc., thus delaying Hughes' purchase of the Landmark and threatening its planned opening. Sun Realty alleged that it was owed a $500,000 finder's fee for locating Hughes as a buyer. The case was dismissed on June 25, 1969. On June 30, 1969, Sun Realty appealed the decision but was denied that day as it was unable to post a bond that would pay the $5.8 million worth of claims, filed by approximately 120 other creditors after Plaza Towers Inc. entered bankruptcy. Hughes' $17.3 million acquisition of the Landmark, through Hughes Tool Company, was completed on July 1, 1969, a day after Hughes issued checks to three different entities to complete the purchase: $2.5 million to Plaza Towers; $5.8 million to fully pay unsecured creditors; and $9 million to pay off the Teamsters Union.
