failed to make a profit during the subsequent years of its operation. In October 1969, Sun Realty filed a damages lawsuit against Hughes Tool Company and Plaza Tower, Inc, alleging that the two companies conspired to avoid paying the realty company its $500,000 finder's fee. Aside from the finder's fee, Sun Realty also sought an additional $5 million in punitive damages. In February 1971, the Nevada supreme court rejected the lawsuit, which had sought $3 million by that time. In December 1971, Hughes paid a little over $1 million to purchase of adjacent land located west of the Landmark. Hughes had previously leased the property, which he had been using as a parking lot for the resort. In January 1973, ownership of the Landmark was transferred to Hughes' Summa Corporation, formerly Hughes Tool Company. That year, the Landmark was valued at $25 million in a property appraisal. By 1974, William Bennett and William Pennington made an offer to buy the Landmark, but Hughes raised the price several times, from $15 million to $20 million; they bought the Circus Circus resort instead. In January 1976, the Landmark began offering foreign-language gaming video tapes to its German, Japanese, and Spanish hotel guests, who frequently limited themselves to playing slot machines rather than table games because of language barriers. Summa general manager E. H. Milligan said, "As far as we know, we are the first hotel in Las Vegas to present this service in this manner." The hotel and casino briefly closed in March 1976, as part of a hotel worker strike consisting of nearly 25,000 employees, affecting 15 Las Vegas resorts. The strike lasted two weeks before ending in late March. Hughes died of kidney failure the following month. By May 1977, Summa was financially struggling; that month, the brokerage firm of Merrill, Lynch, Pierce, Fenner & Smith recommended that Summa sell its various holdings, including the Landmark. According to the brokerage firm, the Landmark "has proven highly inefficient for hotel/casino operations and, in the opinion of Summa Corporation's management, does not warrant further investment."

Two feet of water flooded the basement room and shorted out the main power panel, thereby cutting out electricity for the resort shortly before 5:00 a.m. An auxiliary power generator provided lighting
