<I wouldn't want a neighbor's tower/Yagi looming over my backyard...and I love towers!
<The fall zone idea seems like simple good manners.
<I have been loosely involved in dropping 200' BC towers, dropped by cutting the rods at one guy anchor, thus losing all guys on that side.
<They fell absolutely full length, with a few sections not even bent!  
<I think a foundation failure (soil, bolt, gin pole) would drop a crankup to full length.
<Is there any experience available on this?

##  per software,  Trylon self support  towers will  fail  at the junction  of the 4th  and  5th  section..... 40’  above ground. 
UST  designs a weak  spot.... which  is  midway  up  the  3rd  section...  46.5  feet  above ground.   

##  Never seen  a pix  of  either  tower folded  over... as  depicted  above.    40  ft...and  46.5 ft.   So dont  know if  their
design theory  works....or not.
