Lockheed L-049 Constellation, similar to the aircraft that crashed
Paradise Airlines Flight 901A was a passenger flight from San Jose Municipal Airport to Tahoe Valley Airport in the United States. On March 1, 1964, the Lockheed L-049 Constellation(example pictured) serving the flight crashed near Genoa Peak, on the eastern side of Lake Tahoe, killing all 85 aboard. The cause of the accident was the pilot's decision to attempt to land at Tahoe Valley Airport when the visibility was too low. After aborting the attempt, the crew lost awareness of the plane's location as it flew below the minimum safe altitude in mountainous terrain. The pilot likely tried to fly through a low mountain pass to divert to the airport in Reno, Nevada, and crashed into a mountain near the pass. At the time, it was the second-deadliest single-plane crash in United States history. It remains the worst accident involving the Lockheed L-049 Constellation. The Federal Aviation Administration revoked the airline's operating certificate, causing them to permanently shut down. (Full article...)

Castle Bravo was the first in a series of high-yield thermonuclear-weapon design tests conducted by the United States at Bikini Atoll in the Marshall Islands, as part of Operation Castle. Detonated on March 1, 1954, the device was the most powerful nuclear device detonated by the United States and the first lithium deuteride–fueled thermonuclear weapon tested using the Teller–Ulam design. Castle Bravo's yield was 15 megatonnes of TNT (63 petajoules), 2.5 times the predicted 6 megatonnes of TNT (25 petajoules), due to unforeseen additional reactions involving lithium-7, which led to radioactive contamination in the surrounding area. This photograph shows the Castle Bravo nuclear device, known as SHRIMP, in its shot cab.
