Years after, on 22 July 1992, former Chairman of the Joint Chiefs of Staff Admiral William J. Crowe testified to the House Armed Services Committee regarding charges that the Pentagon had concealed evidence about the 1988 downing of an Iranian airliner by the U.S. Navy cruiser USS Vincennes. As Crowe denied the coverup charges, he spoke briefly about Eager Glacier and other efforts to provide U.S. intelligence to Iraq. Crowe said that Pentagon officials had briefed "the pertinent congressional committees" about Eager Glacier on October 5, 6, and 13 October 1987.
