Hi Dan- Here's a link to the Wiki on the Poland tower that for about 17 years stood as the tallest structure on Earth at 2120.67'. The tower failed during a maintenance event in 1991, and was never replaced. http://en.wikipedia.org/wiki/Warsaw_radio_mast Upon its failure, the 2063' Fargo tower regained the prominence it had held from 1963 to 1974. -d
