It's a stolen concept which the Indian web series maker have tried to mould into a story which is based on a fake/imaginative story published by the "Tabloid" of flight Pan am 914 was a Douglas DC-4 with 57 passengers and six crew members that took off from a New York City airport headed for Miami, Florida.The most popular theory is that the plane passed through some kind of time travel or wormhole, and instead of landing in Miami in 1955, it appeared on arrival in Venezuela 30 years later.
Another story published by the Tabloid was a missing airliner (Santiago Flight 513) mysteriously landed 35 years later with a cockpit and passenger cabin full of skeletons.
Manifest series is also abt the same topic.
So, please stop giving Kudos to the makers on this mystery and unique kinda script coz our indian film makers are very good in stealing concepts from worldwide and taking it to their credit to fill their pockets..
