Doctor Who (1963) Season 19 Episode 24 Time-Flight (2)

The Doctor and his companions, Nyssa and Tegan, find themselves on board a Concorde flight in 1982, where they soon discover that they have been transported back in time to ancient Earth. As they explore their surroundings, they stumble upon a group of people who believe themselves to be survivors of a long-lost civilization called Xeraphin. The Doctor soon learns that the Xeraphin's technology enabled them to manipulate time and space, and that they may have inadvertently created a temporal rift that has trapped them in the past.

The Xeraphin, who are desperate to return to their own time, have taken control of the Concorde and plan to use its engines to generate enough energy to create a portal back to their own time. However, in doing so, they risk destroying the Earth and all life on it. The Doctor must convince the Xeraphin to abandon their plans before it's too late, while also figuring out a way to return himself and his companions to their own time.

As the situation grows more dire, the Doctor uncovers a plot by a mysterious alien race to steal the Concorde and use its advanced technology for their own purposes. The Doctor and his companions must race against time to prevent the aliens from acquiring the Concorde and ultimately save the world from destruction.

Filled with action, humor, and mind-bending science fiction concepts, "Time-Flight (2)" is a thrilling adventure that will keep viewers on the edge of their seats. With the fate of the world at stake, the Doctor and his companions must use all their wits and ingenuity to overcome seemingly insurmountable obstacles and save the day.
