The series tells the story of the 1986 Challenger space shuttle disaster. Just 73 seconds after takeoff, the shuttle exploded, taking the lives of all seven crew members on board.

Among those on the flight was high school teacher Christa McAuliffe, who was the first civilian selected to go to space.

“Conversations with the crew’s surviving family members help create a poignant and relatable portrait of the astronauts,” the official description reads. The documentary will explore the “fatally flawed decision process” that led to the explosion.

“Challenger: The Final Flight” premieres on Netflix on Sept. 16.
