Apr 2, 1992:
Mob boss John Gotti convicted of murder
A jury in New York finds mobster John Gotti, nicknamed the Teflon Don for his ability to elude conviction, guilty on 13 counts, including murder and racketeering. In the wake of the conviction, the assistant director of the FBI’s New York office, James Fox, was quoted as saying, “The don is covered in Velcro, and every charge stuck.” On June 23 of that year, Gotti was sentenced to life in prison, dealing a significant blow to organized crime.
John Joseph Gotti, Jr., was born in the Bronx, New York, on October 27, 1940. He rose through the ranks of the Gambino crime family and seized power after ordering the December 1985 murder of then-boss Paul Castellano outside a Manhattan steakhouse. Behind closed doors, Gotti was a ruthless, controlling figure. Publicly, he became a tabloid celebrity, famous for his swagger and expensive suits, which earned him another nickname, the Dapper Don.
During the 1980s, Gotti’s lawyer Bruce Cutler won him acquittals three times. A jury member in one of those trials was later convicted of accepting a bribe to acquit the mob boss. In December 1990, Gotti was arrested at the Ravenite Social Club, his headquarters in New York City’s Little Italy neighborhood. The ensuing trial, which started in January 1992, created a media frenzy. Salvatore “Sammy the Bull” Gravano, one of Gotti’s top soldiers, made a deal with the government and testified in court against his boss. Gravano admitted to committing 19 murders, 10 of them sanctioned by Gotti. In addition, prosecutors presented secret taped conversations that incriminated Gotti. After deliberating for 13 hours, the jury, which had been kept anonymous and sequestered during the trial, came back with a verdict on April 2, 1992, finding Gotti guilty on all counts. The mob boss was sent to the U.S. Penitentiary at Marion, Illinois, where he was held in virtual solitary confinement. On June 10, 2002, Gotti died of throat cancer at age 61 at a Springfield, Missouri, medical center for federal prisoners.

Villanova beats Georgetown for NCAA basketball championship
On this day in 1985, in one of the greatest upsets in college basketball history, the Villanova Wildcats beat the Georgetown Hoyas, 66-64, to win the NCAA Men’s Division I tournament. The victory was Villanova’s first-ever national championship.
Over 23,000 college basketball fans gathered at Rupp Arena in Lexington, Kentucky, for the match-up between the Hoyas, who took home the NCAA championship in 1984, and the Wildcats, who finished the ’85 regular season tied for third place in the Big East conference. On their way to meeting the Hoyas, who were coached by John Thompson, the underdog Wildcats, coached by Rollie Massimino, beat No. 2-ranked Michigan, No. 5-ranked Memphis State and No. 7-ranked North Carolina in tournament play.
During the championship game on April 1, the Wildcats shot 79 percent from the field and nailed 22 of 28 shots, plus 22 of 27 free throws. Wildcats forward Dwayne McCain, the leading scorer, had 17 points and 3 assists. The Wildcats’ 6’ 9 ½” center Ed Pinckney outscored 7’ Hoyas’ center Patrick Ewing, 16 points to 14 and six rebounds to five and was named MVP of the Final Four.
In a March 16, 1987, Sports Illustrated article, Gary McLain, who played starting guard on the championship Villanova team, admitted to using cocaine during the 1985 Final Four tournament and during his team’s visit to the White House to celebrate their victory and meet President Ronald Reagan. McLain, who also confessed to selling drugs while at Villanova, implied that other Villanova players had used drugs, although he wouldn’t name them. McLain entered drug rehab after he was fired from his job on Wall Street for forging a check and company voucher to help support his addiction

Mar 31, 1889:
Eiffel Tower opens
On March 31, 1889, the Eiffel Tower is dedicated in Paris in a ceremony presided over by Gustave Eiffel, the tower's designer, and attended by French Prime Minister Pierre Tirard, a handful of other dignitaries, and 200 construction workers.
In 1889, to honor of the centenary of the French Revolution, the French government planned an international exposition and announced a design competition for a monument to be built on the Champ-de-Mars in central Paris. Out of more than 100 designs submitted, the Centennial Committee chose Eiffel's plan of an open-lattice wrought-iron tower that would reach almost 1,000 feet above Paris and be the world's tallest man-made structure. Eiffel, a noted bridge builder, was a master of metal construction and designed the framework of the Statue of Liberty that had recently been erected in New York Harbor.
Eiffel's tower was greeted with skepticism from critics who argued that it would be structurally unsound, and indignation from others who thought it would be an eyesore in the heart of Paris. Unperturbed, Eiffel completed his great tower under budget in just two years. Only one worker lost his life during construction, which at the time was a remarkably low casualty number for a project of that magnitude. The light, airy structure was by all accounts a technological wonder and within a few decades came to be regarded as an architectural masterpiece.
The Eiffel Tower is 984 feet tall and consists of an iron framework supported on four masonry piers, from which rise four columns that unite to form a single vertical tower. Platforms, each with an observation deck, are at three levels. Elevators ascend the piers on a curve, and Eiffel contracted the Otis Elevator Company of the United States to design the tower's famous glass-cage elevators.
The elevators were not completed by March 31, 1889, however, so Gustave Eiffel ascended the tower's stairs with a few hardy companions and raised an enormous French tricolor on the structure's flagpole. Fireworks were then set off from the second platform. Eiffel and his party descended, and the architect addressed the guests and about 200 workers. In early May, the Paris International Exposition opened, and the tower served as the entrance gateway to the giant fair.
The Eiffel Tower remained the world's tallest man-made structure until the completion of the Chrysler Building in New York in 1930. Incredibly, the Eiffel Tower was almost demolished when the International Exposition's 20-year lease on the land expired in 1909, but its value as an antenna for radio transmission saved it. It remains largely unchanged today and is one of the world's premier tourist attractions.

Mar 30, 1981:
Obsessed Jodie Foster fan John Hinckley Jr. shoots President Reagan
On this day in 1981, John Hinckley Jr. attempts to assassinate President Ronald Reagan in a crowd of onlookers and security personnel--including police and Secret Service officers--outside a Hilton hotel in Washington, D.C. When asked about his motive for shooting the president, Hinckley revealed that he was seeking to gain the attention of the actress Jodie Foster.
After growing up in an affluent family in Oklahoma, Texas and Colorado, Hinckley moved to Hollywood in 1976. That same year saw the release of Martin Scorsese’s dark drama Taxi Driver. Hinckley watched the film some 15 times and apparently strongly identified with the title character, Travis Bickle (played by Robert De Niro). A violent loner, Bickle seeks the attention of a socialite by trying to assassinate a political candidate and later becomes obsessed with protecting a child prostitute by shooting her pimp. The screenwriter, Paul Schrader, based the character on Arthur Bremer, who shot the Alabama governor and U.S. presidential candidate George Wallace in 1972. In his diaries, Bremer expressed that political assassination was a way to escape anonymity and powerlessness.
As was recounted in testimony given at his 1982 trial, Hinckley began--either consciously (according to the prosecution) or unconsciously (according to the defense)--mirroring Bickle. He wore similar clothes, drank the same peach brandy and amassed a collection of firearms. He also became fixated on Jodie Foster, who played the young prostitute in the film. During the 1980 presidential campaign, Hinckley stalked President Jimmy Carter, getting himself arrested in the process when he was caught at the Nashville airport in possession of firearms. After sending him to a psychiatrist, Hinckley’s family cut him off financially. When he read that Foster was attending Yale University in New Haven, Connecticut, Hinckley traveled there repeatedly, all the while seeking some grand gesture he could make that would earn her attention.
On March 30, 1981, Hinckley made his grand gesture, managing to fire six bullets in three seconds at Reagan in the middle of the crowd outside the Washington Hilton. One of the bullets struck Reagan underneath the left arm; it failed to explode on impact, leaving the president seriously injured but alive. Hinckley also shot a police officer and a Secret Service agent and seriously wounded Reagan’s press secretary, James Brady. Upon his arrest, Hinckley reportedly asked the officers if the news would disrupt the Academy Awards ceremony, scheduled for that night. The ceremony was indeed postponed until the following night, only the third time in history that the Oscars had failed to go ahead as scheduled.
At the conclusion of his trial--during which the defense showed Taxi Driver to bolster its case--Hinckley was found not guilty by reason of insanity. He was confined to St. Elizabeth’s Hospital in Washington, D.C., and has remained there ever since. The case led to legislation limiting the insanity plea in several states and, 12 years later, to the signing of the Brady Bill, which required a waiting period and background check on people wishing to purchase a handgun.

Mar 29, 1973:
U.S. withdraws from Vietnam
Two months after the signing of the Vietnam peace agreement, the last U.S. combat troops leave South Vietnam as Hanoi frees the remaining American prisoners of war held in North Vietnam. America's direct eight-year intervention in the Vietnam War was at an end. In Saigon, some 7,000 U.S. Department of Defense civilian employees remained behind to aid South Vietnam in conducting what looked to be a fierce and ongoing war with communist North Vietnam.
In 1961, after two decades of indirect military aid, U.S. President John F. Kennedy sent the first large force of U.S. military personnel to Vietnam to bolster the ineffectual autocratic regime of South Vietnam against the communist North. Three years later, with the South Vietnamese government crumbling, President Lyndon B. Johnson ordered limited bombing raids on North Vietnam, and Congress authorized the use of U.S. troops. By 1965, North Vietnamese offensives left President Johnson with two choices: escalate U.S. involvement or withdraw. Johnson ordered the former, and troop levels soon jumped to more than 300,000 as U.S. air forces commenced the largest bombing campaign in history.
During the next few years, the extended length of the war, the high number of U.S. casualties, and the exposure of U.S. involvement in war crimes, such as the massacre at My Lai, helped turn many in the United States against the Vietnam War. The communists' Tet Offensive of 1968 crushed U.S. hopes of an imminent end to the conflict and galvanized U.S. opposition to the war. In response, Johnson announced in March 1968 that he would not seek reelection, citing what he perceived to be his responsibility in creating a perilous national division over Vietnam. He also authorized the beginning of peace talks.
In the spring of 1969, as protests against the war escalated in the United States, U.S. troop strength in the war-torn country reached its peak at nearly 550,000 men. Richard Nixon, the new U.S. president, began U.S. troop withdrawal and "Vietnamization" of the war effort that year, but he intensified bombing. Large U.S. troop withdrawals continued in the early 1970s as President Nixon expanded air and ground operations into Cambodia and Laos in attempts to block enemy supply routes along Vietnam's borders. This expansion of the war, which accomplished few positive results, led to new waves of protests in the United States and elsewhere.
Finally, in January 1973, representatives of the United States, North and South Vietnam, and the Vietcong signed a peace agreement in Paris, ending the direct U.S. military involvement in the Vietnam War. Its key provisions included a cease-fire throughout Vietnam, the withdrawal of U.S. forces, the release of prisoners of war, and the reunification of North and South Vietnam through peaceful means. The South Vietnamese government was to remain in place until new elections were held, and North Vietnamese forces in the South were not to advance further nor be reinforced.
In reality, however, the agreement was little more than a face-saving gesture by the U.S. government. Even before the last American troops departed on March 29, the communists violated the cease-fire, and by early 1974 full-scale war had resumed. At the end of 1974, South Vietnamese authorities reported that 80,000 of their soldiers and civilians had been killed in fighting during the year, making it the most costly of the Vietnam War.
On April 30, 1975, the last few Americans still in South Vietnam were airlifted out of the country as Saigon fell to communist forces. North Vietnamese Colonel Bui Tin, accepting the surrender of South Vietnam later in the day, remarked, "You have nothing to fear; between Vietnamese there are no victors and no vanquished. Only the Americans have been defeated." The Vietnam War was the longest and most unpopular foreign war in U.S. history and cost 58,000 American lives. As many as two million Vietnamese soldiers and civilians were killed.

Mar 28, 1979:
Nuclear accident at Three Mile Island
At 4 a.m. on March 28, 1979, the worst accident in the history of the U.S. nuclear power industry begins when a pressure valve in the Unit-2 reactor at Three Mile Island fails to close. Cooling water, contaminated with radiation, drained from the open valve into adjoining buildings, and the core began to dangerously overheat.
The Three Mile Island nuclear power plant was built in 1974 on a sandbar on Pennsylvania's Susquehanna River, just 10 miles downstream from the state capitol in Harrisburg. In 1978, a second state-of-the-art reactor began operating on Three Mile Island, which was lauded for generating affordable and reliable energy in a time of energy crises.
After the cooling water began to drain out of the broken pressure valve on the morning of March 28, 1979, emergency cooling pumps automatically went into operation. Left alone, these safety devices would have prevented the development of a larger crisis. However, human operators in the control room misread confusing and contradictory readings and shut off the emergency water system. The reactor was also shut down, but residual heat from the fission process was still being released. By early morning, the core had heated to over 4,000 degrees, just 1,000 degrees short of meltdown. In the meltdown scenario, the core melts, and deadly radiation drifts across the countryside, fatally sickening a potentially great number of people.
As the plant operators struggled to understand what had happened, the contaminated water was releasing radioactive gases throughout the plant. The radiation levels, though not immediately life-threatening, were dangerous, and the core cooked further as the contaminated water was contained and precautions were taken to protect the operators. Shortly after 8 a.m., word of the accident leaked to the outside world. The plant's parent company, Metropolitan Edison, downplayed the crisis and claimed that no radiation had been detected off plant grounds, but the same day inspectors detected slightly increased levels of radiation nearby as a result of the contaminated water leak. Pennsylvania Governor Dick Thornburgh considered calling an evacuation.
Finally, at about 8 p.m., plant operators realized they needed to get water moving through the core again and restarted the pumps. The temperature began to drop, and pressure in the reactor was reduced. The reactor had come within less than an hour of a complete meltdown. More than half the core was destroyed or molten, but it had not broken its protective shell, and no radiation was escaping. The crisis was apparently over.
Two days later, however, on March 30, a bubble of highly flammable hydrogen gas was discovered within the reactor building. The bubble of gas was created two days before when exposed core materials reacted with super-heated steam. On March 28, some of this gas had exploded, releasing a small amount of radiation into the atmosphere. At that time, plant operators had not registered the explosion, which sounded like a ventilation door closing. After the radiation leak was discovered on March 30, residents were advised to stay indoors. Experts were uncertain if the hydrogen bubble would create further meltdown or possibly a giant explosion, and as a precaution Governor Thornburgh advised "pregnant women and pre-school age children to leave the area within a five-mile radius of the Three Mile Island facility until further notice." This led to the panic the governor had hoped to avoid; within days, more than 100,000 people had fled surrounding towns.
On April 1, President Jimmy Carter arrived at Three Mile Island to inspect the plant. Carter, a trained nuclear engineer, had helped dismantle a damaged Canadian nuclear reactor while serving in the U.S. Navy. His visit achieved its aim of calming local residents and the nation. That afternoon, experts agreed that the hydrogen bubble was not in danger of exploding. Slowly, the hydrogen was bled from the system as the reactor cooled.
At the height of the crisis, plant workers were exposed to unhealthy levels of radiation, but no one outside Three Mile Island had their health adversely affected by the accident. Nonetheless, the incident greatly eroded the public's faith in nuclear power. The unharmed Unit-1 reactor at Three Mile Island, which was shut down during the crisis, did not resume operation until 1985. Cleanup continued on Unit-2 until 1990, but it was too damaged to be rendered usable again. In the more than two decades since the accident at Three Mile Island, not a single new nuclear power plant has been ordered in the United States.
