    That 0.99999(recurring infinitely) is actually equal to 1. The heart says that this is impossible, but the head proves that it is.

    3 of my pals said they saw a UFO from a camp site in Devon.

    They said they saw it moving towards them until it got a few hundred yards away, and it looked a bit like an aeroplane on fire. It then shot directly up into the sky, vertically, in the blink of an eye.

    Reminds me of a time I was flying a radio controlled electric model at night, over a camp site in Devon. It was lit up with a great array of high power LED illuminators. As I was flying it - completely silently over the campsite, doing some fairly extreme aerobatics - I could hear voices behind the trees in the camp site going "Whoa, dude! What the fsck is that!!" as it soared silently through the moonless night sky...

    Actually replace "Devon" with "Stillwater, Oklahoma" and that's a true story - a friend and I did this. I'm sure the campers were eagerly reporting a UFO sighting to all their friends the next day, while we were in the next field trying desperately not to laugh out loud.

    I was once reported for being a UFO when on a farm camping in Cornwall one night. It happened when a car drove over an expiring luminous glowstick at that my friend had thrown. It burst and showered over my head so I appeared as if from nowhere, glowing. The driver screeched off and reported an alien landing to the police. I washed it off. The farmer's wife later came and warned us to keep an eye out for ET, after a radio broadcast about the sighting.

    ...You could have all sorts of fun by attaching speakers to it..! :p

    Now that's interesting. I wonder if that's what we saw in Pembroke (post 74 in this thread). A model helicopter that we got the scale wrong on might account for the rotating lateral movements we saw, the vanishing upwards could be the lights being turned off (assuming the lights can usually be remotely turned off on them).

    Any links to the kind of model you're talking about? Size, flying height, lights etc, and can pretty much anybody own and use one in the UK?

    Better yet I've seen R/C Quadcopters for sale for about ?60. I bet you could add a watch battery and some LEDs without overloading it.

    there was strange sightings of UFO's where I live in London... lights reflecting off clouds.. turned out it was cliff richard concert down the road in wembley, the lights were reflecting / refracting ? against clouds / strange atmospheric conditions.. guess that wasn't enough and he had to go on to his wimbledon gig.

    putting washing out on a line on a hot morning.. esp. heavy items.. you see the steam rising from em.

    Hyperreal numbers have infinitessimals, I'm not sure whether 0.999 recurring is 1 under that construct either (probably 1 - e where e is an infinitessimal, I have no proof).

    But when you tell me a number that you would add to 0.999 recurring to get 1, get back to me.

    EDIT: Looks like that 0.9999 recurring is different to 1 in hyperreal numbers, found this quote on wikipedia

    Students easily relate to the intuitive notion of an infinitesimal difference 1-"0.999...", where "0.999..." differs from its standard meaning as the real number 1, and is reinterpreted as an infinite terminating extended decimal that is strictly less than 1.

    So you add an infinite terminating extended decimal to 0.9999 recurring to get 1. You don't have infinite terminating decimals in the set of real numbers, but you do in the hyperreals.

    There are many different types it could have been from something quite small on upwards. You can get 'night fly' blades too, with LEDs and a battery inside the rotor blades. The more powerful RC helicopters can appear to defy gravity in the hands of a capable pilot. Just search for 'Alan Szabo' on YouTube and you'll see what I mean.

    So what do you think about these cases? (its a long video, 1h 30 mins)
