text_A: On November 16, 2018, an express elevator cable broke. Initial reports stated that an elevator with six passengers plunged 84 stories from the 95th to 11th floor. Since express elevators are not accessible from floors within the express zone, a team of firefighters had to break through a brick wall from the parking garage to extricate the passengers, all of whom suffered injuries. Elevators to the 95th/96th floor were closed thereafter pending investigation. Subsequent investigation documented only a controlled descent from the 20th floor to the 11th floor.
text_B: Is it likely that the majority of any ambulances at the scene of the elevator crash left empty?
NO.
