Miscalculation
In this footage, a team of workers carefully places an enormous sheet of glass into the elevator. They even set up a small stand on the ground to support the sheet and make sure it’s not damaged. Unfortunately, they made a massive miscalculation: the sheet of glass is too long to fit inside the elevator. The doors close and the glass is pulled upward as the elevator descends to a lower floor. Then, it shatters. Come on guys… you had one job!
