and other atomic tests conducted in the 1940s and 1950s on Bikini Atoll were still too high and those island natives that returned to Bikini would once again have to be relocated. In September 1979 a delegation from the Bikini/Kili Council came to Wake Island to assess the island's potential as a possible resettlement site. The delegation also traveled to Hawaii (Molokai and Hilo), Palmyra Atoll and various atolls in the Marshall Islands including Mili, Knox, Jaluit, Ailinglaplap, Erikub and Likiep but the group agreed that they were only interested in resettlement on Wake Island due to the presence of the U.S. military and the island's proximity to Bikini Atoll. Unfortunately for the Bikini Islanders, the U.S. Department of Defense responded that "any such resettlement is out of the question". Commemorative and memorial visits In April 1981, a party of 19 Japanese, including 16 former Japanese soldiers who were at Wake during World War II, visited the island to pay respects for their war dead at the Japanese Shinto Shrine. In the early 1980s, the National Park Service conducted an evaluation of Wake Island to determine if the World War II (WWII) cultural resources remaining on Wake, Wilkes and Peale were of national historical significance. As a result of this survey, Wake Island was designated as a National Historic Landmark (NHL) on September 16, 1985, helping to preserve sites and artifacts on the atoll associated with WWII in the Pacific and the transpacific aviation era prior to the war. As a National Historic Landmark, Wake Island was also included in the National Register of Historic Places. On November 3 and 4, 1985, a group of 167 former American prisoners of war (POWs) visited Wake with their wives and children. This was the first such visit by a group of former Wake Island POWs and their families. On November 24, 1985, a Pan American Airlines (Pan Am) Boeing 747, renamed China Clipper II, came through Wake Island on a flight across the Pacific to commemorate the 50th anniversary of the inauguration of Pan American China Clipper Service to the Orient. Author James A. Michener and Lars Lindbergh, grandson of aviator Charles Lindbergh, were among the dignitaries on board the aircraft.
