I always love the way that folk talk about unexplained objects in the air that they cannot classify and then say "It might be a UFO". Well, er, yes - any flying object that can't be identified is a UFO. Doesn't mean it is Aliens or Russians. It can be a UFO and still be a duck after all. Always an amusing idea though - after all, don't aliens have wind-turbines at home that they can vandalise?
This is why I'm glad that the space-time rift opened up in Cardiff - all the rowdy non-terrestrial tourists go there now instead of coming to Bonnybridge like they used to.
