Yes, it is. 'Manifest Flight 828' is indeed based on a true story. The show uses the concept of a flight that experiences a strange time - related phenomenon, which may have been inspired by some real - life reports of unexplained disappearances and time anomalies. By basing the story on something that could potentially have a basis in reality, it draws in viewers who are interested in such mysteries.
The main elements include the flight's sudden disappearance and its return after a long time. Also, the strange experiences of the passengers upon their return. They seem to have some sort of connection to future events, which could be inspired by real - life accounts of people who claim to have had premonitions or experiences that seem to be related to time in an unusual way. Another aspect might be the confusion and investigation that follows their return, as society tries to make sense of what happened to these people.
Honestly, I don't know. It could be inspired by real events, or it could be completely fictional. We'd need more details to make a definite conclusion.
Flight is not a true story. It's likely a work of imagination or based on a fictional concept. Many elements might have been fabricated to make it more engaging and dramatic.
