      Hmm, it could be that the ball lightning didn't actually pass through the outside of the plane, but formed inside the plane. Maybe lightning could vaporize silicon from the inside of one of the glass windows. The passenger windows in planes are usually covered by a pane of plastic, but it's not sealed around the edges, and, if the ball lightning works the way they've described, it should be able to pass around the plastic pane.
      Also, as far as aeroplanes and unusual effects of lightning go, I remember reading somewhere about fireballs that build up on the nosecones of planes flying through thunderstorms. Are those the same as ball lightning if what is being said about it is true? Where would the silicon come from on the nosecone of a jet? Is it fiberglass covered perhaps?

  18. Holes in the Theory by NatePWIII · · Score: 2

    Two things strike me as odd with this. First the ball lightning is supposed to come from silicon in the soil that is somehow ignited by the excessive heat of the original lightning strike. Second, the ball's of lightning are supposed to have passed through completely impermeable objects such as airplane fuselages and glass. These two facts point to a major contradition here. If the ball originally started out ground level it takes a wild imagination to figure out how it remained burning until it reached an elevation of approx. 10,000 feet, where it happened to collide with a moving airplane.

    Furthermore, if it is burning soil (silicon) how in the earth does it pass through solid glass without melting the glass or walls. Somehow I don't think Heisenberg's uncertainty principle applies in this case.

    My suggestion or better yet theory is that this is just another form of static electricity manifesting itself in an interesting form. Much like the St. Elmo's fire often seen on ships in strong electrical storms. The forming of a ball of ionizing atoms makes me think that somehow this may be related to some sort of surface tension phenomena, much like a soap bubble naturally forms into a perfect sphere. Also this would explain the ability of the ball to pass through solid structures since it is merely a concentrated build up of static electricity and not actual "burning particles". You may refute this theory if I'm wrong or if you can bore enough holes into it. But definetly some food for thought.

    He postulated that the incredible forces involved along these fault lines caused the quartz in the rock to super-heat and become almost plasma-like.

    In the lab he took some granite and applied a tremendous amount of pressure to the sample, and when it eventually fractured, his high-speed camera picked up small examples of this "quartz plasma" floating through the air.

    He then speculated that on a larger scale, such as along fault lines, that these quartz-plasma balls of light would naturally be larger.

      I remember this too. However, since quartz is silicon dioxide, it may in fact be the same thing as the NZ discovery, just a different way of achieving the same result. IIRC, the key feature of this type of "ball lightning" was the lack of thunderstorms in the area at the time of the sightings, and apparent clustering of sightings along fault lines. I also seem to remember reading about this in a book, either about lightning/ball lightning, or a famous (infamous?) series of UFO sightings in NZ in the late 70's or early 80's; if it was the latter, ball lightning (and particularly the seismic variety) was offered as a possible explanation.

    It wasn't exactly a "ball", but kinda round in shape. It has a bright yellowish light, just floating and floating, not actually moving a lot.

    DESCRIPTION:
    It was in 1977, while I was doing a go/no-go test of a batch of 10A (junk surplus) silicon full-wave rectifiers of 1960's vintage. My test rig was an AC plug hastily wired to four 'pin' sockets, two neon bulbs and two high voltage diodes -- plugged into what I thought was a circuit-breaker protected outlet. (the circuit breaker was later found to be shorted 'on')


    About halfway through the batch (100% pass rate), a rectifier failed dramatically, producing a sight that has mystified me for 20+ years. I have always described it as a 'bright 4-7 cm strikingly violet plasma-like flame' that shot out of the hole blown in the side of rectifier.

    • Its shape was irregular and (very) roughly conical or pyramidal, with the apex at the hole in the rectifier (described below), and the 'base' extending outward. The base had very spiky rough flame-like projections, but they did not move appreciably, unlike the irregular flames from a bunsen burner with a flame spreader
    • It had a distinct quivering nature (low frequency, amplitude of 4-8mm)
    • It had the kind of optical diffuseness that I recently saw in a display of highly fluorescent aerogels (often described as 'frozen smoke)
    • It had definite borders, but they looked out-of-focus (in retrospect: perhaps high frequency vibration with amplitude if ca 1-2mm?)
    • Its volume and shape appeared to remain constant for the 45 or so seconds I watched it (then curiosity got the better of me, and I switched off the power to see if it would return
    • with the power off, I could see that the silicon junction (a few mm rectangle) was nearly completely vaporized, with the remaining silicon, the metal contacts and the hole in the plastic casing showing distinctly molten edges. the hole was a characteristic 'ejection crater'
    • There was a scrap of very lint-like 'ash' on my bench, which I didn't examine further (alas) believing it was burned casing.


    In short: a quivering bit 'o' silicon lint glowing
