The perils of a single off-kilter stair:
The story:
At Brooklyn's 36th Street subway stop, one of the steps is slightly higher than the others. This causes many many people to trip on their way up the stairs. Filmmaker Dean Peterson set up his camera to capture the stumbles.
Since being posted on Wednesday, the video has racked up more than a million views. The stair is now being fixed:
The dangerous step, it turns out, is a half-inch higher than the others. Stairway design guidelines call for risers to be a minimum of 6 inches and a maximum of 7 inches, according to MTA spokesman Kevin Ortiz. The allowable variance is 3/8 of an inch. It's not clear why the step was built that way, but after the video went viral and reporters started calling, the MTA went to work.
