[TowerTalk] Falling Derrick Tower erection

[Kevin Normoyle]

searching the web, the guys putting up wind turbines have done
some seriously big tiltups. They tiltup 100' 6" tubular poles with a wind turbine on 
top. (with a lot of care and detail to how to do it)

they fix the gin pole at right angles to the tower, and use a lot of guys/lifting
wires.

or with almost nothing on top (wind monitoring for instance)
