TODAY IN HISTORY

On Nov. 21, 1942, the Alaska Highway, also known as the Alcan Highway, was formally opened at Soldier's Summit in the Yukon Territory.

On this date:

In 1789, North Carolina became the 12th state to ratify the U.S. Constitution.

In 1864, President Abraham Lincoln signed a letter expressing condolences to Lydia Bixby, a Boston widow whose five sons supposedly died while fighting in the Civil War. (As it turned out, only two of Mrs. Bixby's sons had been killed.)

In 1922, Rebecca L. Felton, a Georgia Democrat, was sworn in as the first woman to serve in the U.S. Senate; her term, the result of an interim appointment, ended the following day as Walter F. George, the winner of a special election, took office.

In 1927, picketing strikers at the Columbine Mine in northern Colorado were fired on by state police; six miners were killed.

In 1934, the Cole Porter musical "Anything Goes," starring Ethel Merman as Reno Sweeney, opened on Broadway.

In 1967, President Lyndon B. Johnson signed the Air Quality Act.

In 1969, the Senate voted down the Supreme Court nomination of Clement F. Haynsworth, 55-45, the first such rejection since 1930.

In 1973, President Richard Nixon's attorney, J. Fred Buzhardt, revealed the existence of an 18-1/2-minute gap in one of the White House tape recordings related to Watergate.

In 1974, bombs exploded at a pair of pubs in Birmingham, England, killing 21 people. (Six suspects were convicted of the attack, but the convictions of the so-called "Birmingham Six" were overturned in 1991.)

In 1980, 87 people died in a fire at the MGM Grand Hotel in Las Vegas, Nevada. An estimated 83 million TV viewers tuned in to the CBS prime-time soap opera "Dallas" to find out "who shot J.R." (The shooter turned out to be J.R. Ewing's sister-in-law, Kristin Shepard.)

In 1985, U.S. Navy intelligence analyst Jonathan Jay Pollard was arrested, accused of spying for Israel. (Pollard later pleaded guilty to espionage and was sentenced to life in prison; he was released on parole on Nov. 20, 2015.)

In 1992, a three-day tornado outbreak that struck 13 states began in the Houston area before spreading to the Midwest and eastern U.S.; 26 people were killed. Sen. Bob Packwood, R-Ore., issued an apology but refused to discuss allegations that he'd made unwelcome sexual advances toward ten women over the years. (Faced with a threat of expulsion, Packwood ended up resigning from the Senate in 1995.)
