On June 14, 2017, an emergency call from London council housing Grenfell Tower reported a small fire on the fourth floor of the building. 36 minutes later the fire climbed to the top of the 24 story building. While residents called for help from within, family members and neighbors watched in horror from the street. 72 people died. Many recorded the event. People were told by authorities to stay in their homes, a standard practice with fires in high-rise buildings. This was based on the theory that the building's design would keep the fire contained. However, a government inquiry later found that the outside of the building had been fitted with highly combustible cladding, which led to the fire spreading quickly, and left residents trapped. Had this been known, the property would have been evacuated and lives saved.
