 * Alberto Lleras Camargo agreed to accept the nomination of both political parties in the South American nation of Colombia to serve as the new president to succeed the five-man military junta that had overthrown dictator Gustavo Rojas Pinilla. Under the terms of the 1956 agreement between the Colombian Liberal Party (PLC) and the Colombian Conservative Party (PCC), an equal number of seats were reserved in both houses of the Congress of Colombia for the two parties, and the presidency would alternate every four years, with the Conservatives to select the 1958 president, subject to the approval of the Liberals, and for the 1962 president to be picked by the Liberals.  Since a majority of the Conservatives did not approve of their moderate member, Guillermo Leon Valencia (who would have been acceptable to the Liberals), the parties amended their agreement to let Lleras Camargo, Director of the Liberal Party, to serve first, with the Conservatives to pick the 1962 candidate.  Dr. Lleras resigned from the Liberals in his acceptance speech and said, "I consider myself obligated to represent both parties equally."

 * The U.S. Navy conducted an experiment to determine how high a basketball would bounce if dropped from the top of the Empire State Building.

"This is no frivolous stunt," Lieutenant Commander John Hannigan told reporters, adding "Continual developments of our bombing accuracy for anti-submarine missions demand constant practice in dropping missiles with varying ballistics." The test showed that a basketball dropped from the Empire State Building would bounce back up no higher than 22 feet, nine inches (6.98 meters).
