This reminds me of a story I heard when I was stationed at the CG LORAN station
in Sylt,
Germany. The Norwegians manned a LORAN station on the island of Jan Mayen which
had a 625ft tower as transmitting antenna. This antenna had stood for many years
with-
standing everything the Arctic weather could throw at it. Then one Summer a new
engineer
was sent to do the annual tower inspection. He determined that the guy tension
was too
high and ordered it reduced. Needless to say, that Winter the tower iced up and
came down!
Engineers can get it wrong too!

I offer my condolences to Radio Arcala, but I have a question about that
explanation: shouldn't the engineering of the tower system have accounted
for the possible failure of a windload-mitigation system?
Does anyone know: was it insured?

A sad day in Finland, the fantastic, now doomed, 330ft monster tower for 80
and 160 had a catastrophic failure during a high wind storm in September.
Apparently the engineering spec called for an automated feature to turn the
massive array for minimum windload failed, allowing the whole structure to
"corkscrew" and collapse on itself.
