People rescued from a trapped lift in one of Chicago's tallest skyscrapers later learned they had dropped 84 floors.
The Chicago Tribune reported on Monday that six people, including a pregnant woman, got into the lift early on Friday after leaving a restaurant on the 95th floor of the 875 North Michigan Avenue building, formerly the John Hancock Centre.
They heard noises and experienced a faster and bumpier than expected ride.
One of several cables holding the lift broke and the car fell rapidly, landing somewhere near the 11th floor.
Firefighters broke through a wall more than 10 stories above ground from a parking garage to reach the people who were trapped inside.
The lift and two others will be closed until repairs are made and officials figure out what happened.
