Anyway, I have to argue about flying saucers on the beach with people, you know. And I was interested in this: they keep arguing that it is possible. And that's true. It is possible. They do not appreciate that the problem is not to demonstrate whether it's possible or not but whether it's going on or not.

It is not unscientific to make a guess, although many people who are not in science think it is. Some years ago I had a conversation with a layman about flying saucers — because I am scientific I know all about flying saucers! I said “I don’t think there are flying saucers”. So my antagonist said, “Is it impossible that there are flying saucers? Can you prove that it’s impossible?” “No”, I said, “I can’t prove it’s impossible. It’s just very unlikely”. At that he said, “You are very unscientific. If you can’t prove it impossible then how can you say that it’s unlikely?” But that is the way that is scientific. It is scientific only to say what is more likely and what less likely, and not to be proving all the time the possible and impossible. To define what I mean, I might have said to him, "Listen, I mean that from my knowledge of the world that I see around me, I think that it is much more likely that the reports of flying saucers are the results of the known irrational characteristics of terrestrial intelligence than of the unknown rational efforts of extra-terrestrial intelligence." It is just more likely. That is all.

Seriously. UFO organisations have been contracting of late, because no-one's seeing flying saucers any more. They turn up at weird cultural stress points, like an approaching millennium (which the X-Files lucked into, rather than caused). Almost, it seems, when the culture is worried about something amorphous rather than concrete (like terrorism). The 90s UFO "glut" coincided with the threat of nuclear war fading, relative political stability in the US and UK, and yet the feeling that the turn of the century Meant Something that we couldn't put into words. I almost miss flying saucers: because they might mean that we don't have anything serious to worry about.

Where have I been? I've been on my flying saucer tour. Which means like flying saucers I too have been appearing in small southern towns in front of a handful of hillbillies lately...no one doubts my existence.

My brother and I became seriously interested in the problem of human flight in 1899 ... We knew that men had by common consent adopted human flight as the standard of impossibility. When a man said, “It can’t be done; a man might as well try to fly,” he was understood as expressing the final limit of impossibility. Our own growing belief that man might nevertheless learn to fly was based on the idea that while thousands of the most dissimilar body structures, such as insects, fish, reptiles, birds and mammals, were flying every day at pleasure, it was reasonable to suppose that man might also fly... We accordingly decided to write to the Smithsonian Institution and inquire for the best books relating to the subject.... Contrary to our previous impression, we found that men of the very highest standing in the profession of science and invention had attempted to solve the problem... But one by one, they had been compelled to confess themselves beaten, and had discontinued their efforts. In studying their failures we found many points of interest to us.
At that time there was no flying art in the proper sense of the word, but only a flying problem. Thousands of men had thought about flying machines and a few had even built machines which they called flying machines, but these were guilty of almost everything except flying. Thousands of pages had been written on the so-called science of flying, but for the most part the ideas set forth, like the designs for machines, were mere speculations and probably ninety per cent was false. Consequently those who tried to study the science of aerodynamics knew not what to believe and what not to believe. Things which seemed reasonable were often found to be untrue, and things which seemed unreasonable were sometimes true. Under this condition of affairs students were accustomed to pay little attention to things that they had not personally tested.

They may be a quarter million years more advanced than we are technologically. Their technology will look like magic to us. I don't think that we should be running around thinking these are gods in flying saucers that we should worship. We need to take this in a very rational way.
