[TowerTalk] OH8X 80-160 monster tower collapses

[Roger D Johnson]

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!

73, Roger
