LAS VEGAS - A hotel-casino that opened in 1955 as the Showboat and was more recently known the Castaways collapsed into history Wednesday when it was demolished by implosion.
From the North Lake Tahoe Bonanza:
The 19-story tower, which stood alone about three miles east of downtown Las Vegas, had been closed since changing hands in a bankruptcy proceeding in January 2004.
A staccato series of explosions reduced the 447-room building as planned into a 20,000-ton heap of rubble and raised a huge cloud of dust just after dawn on a sparkling clear morning.
