The memorial, which includes wreckage of a downed U.S. B-52, was used as a location where contestants hunted for clues. The Veterans of Foreign Wars and American Legion organizations had criticized CBS over the show’s use of the memorial. Two Americans were killed when the bomber went down. The segment also included a choir singing a tribute to the Vietnam Communist Party. “Parts of last Sunday’s episode, filmed in Vietnam, were insensitive to a group that is very important to us — our nation’s veterans,” said the CBS statement, read before the start of tonight’s episode.
