Dashcam footage taken Saturday captured the terrifying moment a crane collapsed in Washington, killing four people.

The footage showed a car traveling up to a traffic intersection in Seattle around 3:30 p.m. Suddenly, a large red crane atop Google's new campus toppled over and fell apart onto Mercer Street down below.
