Have you ever looked up at the night sky, saw a light moving and didn’t know whether it was a plane or a meteor? It happens. But if you had this flowchart, you’d be able to identify 90% of all moving lights in the sky. Roughly.

This flowchart by the League of Lost Causes is designed to teach you to use your deduction skills to correctly lights in the sky according to whether they move, their sizes and other characteristics. It’s even available as a poster, postcard and a mug.

    as suggested by zubair zahoor, they should have added superman

    the flowchart would look like this:
    is it a bird? no is it a plane? no
    then it's superman!

    If they are moving then they are all UFO's until you I them. Maybe someone should make a chart.

      Is it moving? Yes: UFO; no: a hovering UFO.

    It also leaves out iridium satellite flares which can be extremely bright and move at a constant speed, faster than an airplane and slower than a meteor.

    I saw a moving object travelling from north to south. I started to drop towards horizon. Then I noticed it was between me and a building a few blocks away. What I found was a pillow sized parachute with a half-burned wick. Mystery solved.

      Lol that's genius. Why would he need a flashlight though?

    For anyone interested in ufo's Google what happened in rendelsham forrest in England.

    Not only were the craft picked up on radar but it landed in the forrest and was examined by a group of men from the nearby US ran military base. It left three indentations, where the landing pads had come down, and crystallized the structure of the soil direcrly beneath where it had landed.

    The official story is that they were seeing a lighthouse about 1000 meters away... ok, tell me why a group of trained observers all came to the same conclusion that it was not, nor could it have been, a lighthouse.

    I understand this article is a joke, but here's what happened to me: One night during my teenage years my sister and I were riding on the back of our dad's pickup truck (the destination eludes my memory). We were both looking up at the sky and both of us at the same time saw that all of a sudden a "star" started to move. It looked extremely far away, so I don't think it wa she ISS, especially because it wet from a standstill to a constant rate of motion (it didn't accelerate). According to this chart, it was an artificial satellite, but due to the apparent distance and rate of movement, I could only conclude it was the option left off this chart: a UFO.

      You may be right, except for the little detail that none of the other stars started moving. Oh, and we had just gotten to a stop light. :-)

    Come one folks; are can't believe anyone would take this flow chart in any other way but tongue in cheek.....jeez!

    There is one option that has been left of the chart - a UFO. There have been many sightings of those, although the authorities have always try to explain them away in terms of the other possibilities on the chart.

      The nature of the chart eliminates the inclusion of an Unidentified Flying Object.

      "The nature of the chart eliminates the inclusion of an Unidentified Flying Object."
      Only if you exclude UFOs a priori. The chart includes four non-natural objects already: an airplane, International Space Station, artificial satelite and masthead light, so a UFO fits right in.

      The input to the flowchart is an unidentified object. Since the intent of the flowchart is to identify this object, you can't have an unidentified object, flying or otherwise, as the output.

      Sorry, Larry. Please read the first sentence. The input is a "moving light", not "moving object."

      I think you are right. This flowchart is a humourous one, people.

    I think this is more a joke than a helpful chart.
    "Are any astronauts waving at you?" -yes-> "International Space Station"

    Funny though.
