- I worked for GE when this happened, it was in 1982 or 1983. If I recall,
- the tower was going to be 2200 feet, with the current tallest being 2063 feet
- (located in North Dakota).

-
- When towers are constructed, they use a device called a "jib pole". It is
- a small rod that is attached to the top of the tower and stick up in the
- air about 20 feet. The jib pole is used to raise a section of tower and
- hold it while it is being bolted in place. Once a section of tower is put
- up, the jib pole is raised, and the process is repeated.
-
- Since the jib pole is moved dozens of times during construction, it needs to
- be very light. They are designed to hold the weight of one tower section.
- The mistake that was made is that two construction workers decided to ride
- up to the top of the tower on the tower section that was being lifted up
- by the jib pole. The jib pole was not strong enough to carry the additional
- weight, and it collapsed. When it did, the load fell to the ground, killing
- the two workers who were riding on the load. The sudden change in tower
- loading coupled with the fact that the final supports were not in place yet
- caused the tower to collapse. The tower folded up much like an acordion.
-
- The final accident report blamed the construction supervisor for allowing
- the two workers to ride on the load that was being hoisted even thought it
- was against OSHA rules. Had they followed the rules, the accident would
- not have happened. In fact, they were very lucky that more people were not
- killed.
