Fifteen years after the attack, an Israeli pilot approached Liberty survivors and then held extensive interviews with former Congressman Paul N. (Pete) McCloskey about his role. According to this senior Israeli lead pilot, he recognized the Liberty as American immediately, so informed his headquarters, and was told to ignore the American flag and continue his attack. He refused to do so and returned to base, where he was arrested.Later, a dual-citizen Israeli major told survivors that he was in an Israeli war room where he heard that pilot's radio report. The attacking pilots and everyone in the Israeli war room knew that they were attacking an American ship, the major said. He recanted the statement only after he received threatening phone calls from Israel.
The pilot's protests also were heard by radio monitors in the U.S. Embassy in Lebanon. Then-U.S. Ambassador to Lebanon Dwight Porter has confirmed this. Porter told his story to syndicated columnists Rowland Evans and Robert Novak and offered to submit to further questioning by authorities. Unfortunately, no one in the U.S. government has any interest in hearing these first-person accounts of Israeli treachery.
Taken from here. Some interesting differences.
Reference to Evans and Novak's story can be found here:

According to this report, Evans and Novak took liberties with some of the sources - not difficult to imagine.
"In 1991, columnists Rowland Evans and Robert Novak trumpeted their discovery of an American who said he had been in the Israeli war room when the decision was made to knowingly attack the American ship.4 In fact, that individual, Seth Mintz, wrote a letter to the Washington Post on November 9, 1991, in which he said he was misquoted by Evans and Novak and that the attack, was, in fact, a "case of mistaken identity." Moreover, the man who Mintz originally said had been with him, a Gen. Benni Matti, does not exist."
All things considered, the case is intriguing, but far more damage is done by unapologetic statements from Spector (calling the men of the Liberty "fools"), than from any historical fact which has come to light.
