Original Text

When Hartley contacted LeMessurier’s firm about the issue they assured her the building was strong enough to handle these winds. But checking the plans again, LeMessurier noticed an alarming detail. A change approved without his knowledge had replaced the exoskeleton’s welded joints with cheaper and weaker bolted joints. This alone wasn’t enough to topple the tower thanks to the mass damper. But if a storm knocked out the building's power, it would deactivate the counterweight’s sensors, leaving the building vulnerable to winds of just 112 kilometers per hour. Given available weather data, a storm this strong had a one-in-sixteen chance of hitting New York City every single year.
