Rating: 9/10 (4 June 2020)

It touches the incredibly sensitive topic, September 11 attack. Few hours into the infamous day: what happened, especially to the 4th plane and the people in it? It's tensed and heart wrenching but you should watch to experience it. It will leave you relentless and speechless for sometime.
Unlike Paul Greengrass' Green Zone, it recounts the actual event without much of grey areas.
