'Time traveller' claims secret machine sent him from 1977 to 4413

A man named Lewis Walker says he traveled through time.

He says he worked for Britain's Ministry of Defence in 1977.

Government scientists asked him to test a secret time machine.

They offered him a lot of money, £250,000, but warned there was only a 50 percent chance he would make it back.

He says a helicopter took him to a secret underground base under the English Channel.

Inside, a big triangular machine sent him to the year 4413.

When he woke up in an empty hospital, a robot voice told him humans no longer lived there and robots ran the city.

He met a man who said he was also a time traveler, from the year 2030.

Walker went to a place called 'Time Station' and chose to return to 1977.

The scientists told him he had been gone for weeks, but he showed no proof of any of it.
