[TowerTalk] Collapsed KFI Tower -- Impact of Coax?

[Tower]

Even tall, unguyed structures tend to fall in on themselves although they 
would form as close a knit pile as the guyed tower.
The acelleration of a tall tower tipping over will cause the top half of so 
to bend back on itself.

I'd sure hate to have the liability of a tower near final approach to any 
airport.

A few years back a TV station installed a tower near HTL. Actually it was 
within the 5 mile radius of HTL and they didn't even have permit, nor had 
they gone through the paperwork with the FCC and FAA.
I believe the top of the tower is near or over 900 AGL.   BTW that tower is 
almost in the pattern for a public gras strip near the SW corner of Houghton 
Lake.  You have to watch out for the guy wires when landing to the north and 
when you take off you have to go around the state police tower about a half 
mile off the end of the runway.

The tower had been constructed, but there weren't even any lights on it yet. 
Not even any part way up.

The tear down order had been written, but they pleaded and received a 
reprieve.
