here's a link to an aerial video via helicopter:
mike - i was in bellevue last december and i was really taken aback by the number of tower cranes in bellvue. quite a few.
does anyone know who's site this was? i'm familiar with only one highrise contractor though i'm sure there are many. tishman is the only one i know of by name.

you should have gone across the lake to seattle - twice the number. almost makes it look like we're not in a recession...

i read in a local news article that this collapse was apparently caused by a piece of falling steel that hit the strut that attached the crane to the building - a freak accident.
here's a link to a story in today,s ny daily news about the crane subcontractor:
here is one of the nyt articles on the collapse that identifies a support collar that fell, while being attached, and sheared a lower support.
here is a little more information on the suspected cause of the crane collapse.
the crane inspector has now been arrested for falsifying records !
here is a report on the actions taken by the city in reference to the post by robertmetfff">.
