The show 'Hijack' is not based on any true events. It's the product of the imagination of the writers and creators, designed to provide an exciting and captivating viewing experience without being tied to reality.
I'm not entirely sure about a specific 'hijack' full story within 'Diya Aur Baati Hum'. It could be a fan - made or a very specific plot point that might not be widely known. Maybe it was a situation where a character was in a vehicle that got hijacked during a particular mission or journey in the story.
One common plot twist could be that the hijacker is not who they seem. Maybe they are being forced to hijack the plane by some unseen villains. Another could be that there is a secret agent among the passengers who manages to turn the situation around. And sometimes, the destination the hijackers claim to be aiming for is just a decoy, and they have a completely different and more sinister plan in mind.
Sure. There was once a plane that got hijacked. The hijacker demanded to go to a remote island. But as the plane flew, a brave flight attendant managed to secretly send a distress signal. The authorities then found out that the hijacker was actually a man who had lost his family in a government - related accident and was trying to make a statement. In the end, the pilot tricked the hijacker into thinking they were landing on the island while actually landing at a military base where the hijacker was apprehended without any harm to the passengers.
