According to witnesses, a "gauntlet" of male military officers in civilian clothes groped, molested, or committed other sexual or physical assaults and harassment on women who walked through the hallway.
In response, the United States Congress, led by the Senate Armed Services Committee, directed the US military to investigate the event, verify the allegations, and prosecute the personnel involved.
Three officers were taken to courts-martial, but their cases were dismissed after the presiding military judge determined that Chief of Naval Operations Frank Kelso, who had attended the conference, had concealed his own involvement in the events in question.
[8] In spite of continued exhortations and warnings from Tailhook leadership, subsequent conventions returned to featuring excessive alcohol consumption, sexually explicit presentations and activities, and lewd behavior by attendees.
The custom involved young aviators lining up on both sides of the east wing third floor hospitality suite hallway and slapping stickers of their squadron insignia on the bodies of passersby, usually women.
[12] The 1991 Tailhook convention, formally titled "The 35th Annual Naval Aviation Symposium" and scheduled for September 5–8 at the Las Vegas Hilton, was expected to be the largest in the organization's history.
The Gulf War had taken place earlier in the year, and over eleven hours of presentations and discussion concerning US Navy and Marine Corps aviation operations in the conflict were to be the central focus for the 4,000 attendees.
Dunleavy replied, "If Congress directs SecNav (the secretary of the Navy) to allow qualified women to fly combat aircraft, we will comply," which drew more boisterous boos and catcalls from the audience.
Just past midnight, Tailhook partiers in an eighth-floor room, "mooning" the spectators, accidentally pushed out a window, and the large pane of glass plummeted into the crowd around the pool and shattered on the concrete.
"[29] Gregory Vistica, a journalist with the San Diego Union obtained a copy of Ludwig's letter and, on October 29, 1991, his newspaper published an article on Tailhook 1991 titled, "Women reportedly abused by Navy pilots at seminar."
McCain later wrote a letter to Chairman of the Joint Chiefs of Staff Colin Powell and United States Secretary of Defense Dick Cheney requesting that an independent commission investigate the matter, but the DoD declined.
The political climate at that moment may have contributed to the reaction to the story, as the contentious Clarence Thomas Supreme Court nomination hearings, involving allegations of sexual harassment, had concluded two weeks earlier.
[32] Angered over the firing of Snyder, naval aviation officers began telling reporters that Garrett had been present at Tailhook and had been made aware of the September 7 gauntlet incident by the next day.
The report did not blame any individuals by name, but it found "a marked absence of moral courage and personal integrity" in the officers interviewed, whom investigators faulted for failing to accept responsibility for their actions.
[36] A number of members of Congress, including Sam Nunn, John Glenn, Barbara Boxer, and Pat Schroeder, were dismayed with the limited scope and results of the NIS investigation, which appeared to have avoided any inquiry into the culpability of commanders or other higher-ranked officers in the incident.
The methods reportedly included physical intimidation, lying, trickery, badgering, harassment, innuendo, and false accusations as well as standard law enforcement techniques like "good cop/bad cop.
Reason also wanted letters of censure for three other officers (Frederic Ludwig, Robert E. Stumpf, and Richard F. Braden) that he had decided not to offer nonjudicial punishment to but who his legal team also said had cases that were too weak for trial.
Peairs and Yakeley were accused of indecent exposure, Braden of witnessing the gauntlet and not intervening, Stumpf of allowing lewd acts to occur in his squadron's suite, and Ludwig for his role in planning and directing the convention.
[62] After resuming on October 14, 1993, James T. Kelly, a civilian employee at Patuxent and Navy Reserve P-3 tactical coordinator who attended Tailhook '91, testified at the hearing that he had witnessed the assaults on Rodgers and Coughlin.
[66] Cowden's article 32 hearing convened on July 15, 1993 and his defense attorney effectively attacked the credibility of the accuser, whose account of the assault had changed over time and who admitted to lying to investigators.
Reason, however, based on advice given him by his staff judge advocate Captain Jeffry Williams, dropped the sexual assault charge but decided to proceed with a general courts-martial for conduct unbecoming.
[69] On September 10, 1993, acting on a motion from Cowden's attorney, Vest ruled that Williams "had exceeded permissible bounds of his official role as a legal advisor" and disqualified him from the case.
[72] At his article 32 hearing on August 3, 1993, Diaz told the court that Remshak had never given him such an order, and if he had it did not matter because senior officers, including Dunleavy, Vice Admiral Edwin R. Kohn, Jr., and Kelso had witnessed the activity and had tacitly approved it by not intervening.
In response to Diaz' statement on August 3, the Office of the Chief of Naval Information issued a press release saying that at the '91 convention Kelso "did not visit any of the squadron suites, nor did he see or hear of any misconduct or inappropriate behavior.
Thirty-four witnesses, mainly junior and mid-level officers (O-5 and below), testified or provided sworn statements that they had seen Kelso in the suites or pool patio area on Saturday night around the same time that the crimes committed by Tritt, Miller, and Samples had allegedly occurred.
[100] The SASC's perceived intransigence over its promotion approvals for Tailhook-implicated, but cleared, officers like Stumpf drew criticism, including from former Navy Secretary Jim Webb and the editorial board of the Wall Street Journal.
Sam Nunn, one of the senior members of the SASC, reacted angrily to the criticism in a hearing on March 12, 1996, saying, "What I deeply resent is the pounding this committee has taken on procedure, as if you've got some kind of McCarthy trial going on.
We hope this is the beginning of a measured re-examination of the injustices accorded to hundreds of naval officers whose promising careers were terminated prematurely during the shameful political hysteria following the 1993 investigations.
[111] At the same time, the Air Force announced it was also admitting women into combat flying slots, and introduced Jeannie Leavitt and Sharon Preszler as its first female fighter pilots, followed soon after by Martha McSally.
Hansen's home state Senator, David Durenberger, however, demanded that Arthur's name be withdrawn from future command nominations, and Navy CNO Boorda acquiesced on June 24, 1994.
