Commentator is terrible.  "At this site, you can see 55miles to the horizon."  dang.  Impressive line to read.  Sounded like he was reading it to a 2 year old.
I am not "afraid" of heights.  I do however give them the respect they deserve.  As always, it is not the fall, it is the sudden stop at the bottom.  1700+' ???  Try going 105' on the aerial truck at the fire department on a windy day.  Even on a "nice" day with a breeze it can get chilly at these such heights.  Aerial truck extended all the way can be a bit nerve racking when it stops moving, yet keeps swaying 4-6' back and forth for awhile.  I cannot imagine what it must feel like on top of this antenna.  I will just sit back with TF eating Cheetos and applaud when he comes down!
