Four people were killed when a 98-foot section of a departure lounge roof collapsed in Terminal 2E at Paris’ Charles de Gaulle Airport on May 23 at about 7 a.m.

The new Air France terminal, completed less than a year before in June, was evacuated, and French authorities are contemplating tearing it down. The terminal handled about 60 flights a day.
