Hi Len
The only document and data I have found is a letter written to a Mr. Richard
Ramirez at WHCT-TV in Hartford, CT. by Mr. Gunnar Olsen, Jr., P.A.,P.E.

I obtained my copy from Tower Tech, PO Box 572, Woodinville, WA. 98072

The letter is in draft form and discusses an engineering study performed by
Mr. Olsen of a number of guyed towers that collapsed during the past 40
years. The study indicates all of the debris from a standard multiguyed tower
will fall within a circle with a radius which would not exceed 29 percent of
the tower height. And, 95 percent of the debris falls within a 20.6 percent
radius of the tower height.

My copy of the letter is a multi generation copy that is readable but poor
quality. You might find a better copy. However, if not I will be happy to
mail you a copy of what I have. This letter was included with my application
and satisfied, in part, the request of my Zoning Board and City Council.

Hank,
There is a draft engineering report in the form of a letter for GUYED towers
that shows extensive data on collapsed towers. I obtained my copy from "Tower
Tech," operated by Steve, K7LXC at aol.com. The report is in the form of a
letter from Gunnar Olsen, Jr P.A.,P.E. to Richard Ramirez at Astroline
Communications Co., WHCT-TV, Hartford Conn.

My copy is a many generation copy but if you cannot find one I'll be happy to
send you one. I was successful in getting the setback requirement reduced.

Good luck
