Cold War would have been East versus West.

There would have been a nuclear arms race.

There would have been spying, a general distrust between two areas of the world.

And that builds a real unease amongst the population, so much so that if you see something in the sky, is that alien or is that Russian?

Either way, it's a threat.

Well, it could be, but I think there are other environmental-type explanations that we need to consider.

And that's the possibility that we're dealing with some form of poisoning.

And before you interrupt me, let me explain.

Betty had in the car nitrate in the form of fertiliser.

Hold on a second.

Why has she got fertiliser on her holiday?

She's doing a cheeky bit of gardening on the side.

Well, she might be.

I wish we had Betty in front of us to ask, why did you have...

Well, we know that you can have nitrate poisoning.

And potentially what we've got is also cross-contamination.

If they've got...

nitrates here in the form of fertilizer but they've also got picnic food and cooking equipment if you've got that you know it's not the sort of thing that over all of their long drive that it would be inducing hallucination in itself but it could be a really strong component i'm going to put you on the spot barney looks up he sees a craft with windows he sees faces through those windows

Yeah, why couldn't it be a hallucination?

We've got countless cases and countless examples of people having hallucinations where they're able to provide detail.
