An investigation is under way after dozens of people dangled more than 100 feet in the air for hours in a Bronx Zoo cable car Wednesday evening.

Guests hung suspended in the air for five hours after one of the wheels on a Skyfari car became separated from the cables, causing the ride to come to a halt. Rescue workers removed three passengers from that car three hours after the ride stopped. However, it took another two hours for crews to repair the system and allow the other passengers to unload.

The Skyfari ride, last inspected on Memorial Day, is closed for the time being.

All the passengers made it out safely. The zoo apologized to the stranded visitors and their families for the incident.
