"Four Killed When Copter Hits Tower"
''Chicago Tribune'', February 15, 1968, p1B-8 The television station was off the air for eight days, finally resuming broadcasts from their previous (KOVC) tower. A replacement mast of the same height as the one destroyed was completed in four and a half months. The second mast fell during an ice storm which hit the area on April 6, 1997, subjecting it to wind gusts of 70 mph and causing at least four inches (100 mm) of ice to accumulate on the structure, resulting in the structure's failure at 6:09 P.M.. Cable programming was resumed by 8:34 and broadcasts by 3 P.M. the following afternoon through coordination with other affiliates; a 735-foot (224 m) temporary tower was completed and resumed broadcasts by July 10. This tower, known as KXJB-TV Mast 2, still stands next to the full-height mast. Work began on replacement of the full-height mast with a more durably-built structure on April 1, 1998, and had reached the tower's previous height by July 30. That day members of the construction crew affixed a four-foot (1.2 m) flagpole to the top of the tower, making the structure's height effectively 2064 ft (629 m), or one foot higher than the KVLY mast (the flagpole was later removed). Broadcasting for Channel 4 was switched to the new mast on August 15.
