1 Caption: Mars, 1947:
1 Martian 1: Make a recon flight over Mt Rainier in Washington.
2 Martian 2: What if a human sees us?
3 Martian 1: Fly erratically. Skip across the sky like saucers skipping across a lake. Nobody will believe their eyes.
4 Martian 2: So... you want our flying saucers to behave like... flying saucers?
4 Martian 3: Brilliant!

The modern UFO age began in June 1947, when pilot Kenneth Arnold reported seeing unusual flying objects near Mt Rainier in Washington. He described them as saucer shaped and as skipping "like saucers" across a lake. Arnold's actual statements varied slightly over time, but the early reports got into the newspapers and fired the imaginations of readers and writers alike, so that very quickly people all over the USA were talking about "flying saucers".
