The hypothesis of the OP is that the spiral could not have been caused by the Bulava. By using the parameters specified by the OP it is shown that this is not the case.
Waveforms do not radiate in spirals. "Spiral waveform" is a contradiction in terms. A circular waveform is possible, a spiral is not. A wave is a transfer of energy through a medium in which the medium itself shows no net movement. What is displayed in the spiral is the constant radial motion of material outward from a rotating central point, like a lawn sprinkler.

No you have it correct now it was Phage the FARRTist
Based on a presumed distance of 971km, the height and exhaust velocity are consistent with a missile. The distance makes it consistent with being the Bulava missile. A range in distance of 600 km still gives acceptable figures:
At 671 km the height is 290km, the diameter 19.6km, and the velocity is 1.2km/s
At 1,271 km the height is 709km, the diameter 40.1km, and the velocity is 2.5km/s
The OP has not disproved the Bulava.
August 12, 1986, 10 p.m. Hundreds of thousands of people were outside in the eastern half of the United States, looking for Perseid meteors. Many of them had their astronomical instruments and cameras at the ready.
Suddenly a bright, fuzzy spiral, wider than the moon, appeared in the eastern sky, moving from right to left. Sightings occurred from Georgia (Florida was socked in with clouds) to Texas, from Oklahoma City to Quebec, Canada, and all points in between.
Wayne Madea, an amateur astronomer in northern Maine, saw a bright starlike object emit a luminous, rapidly expanding donut-shaped cloud; through a telescope he saw “a pinpoint of light, like a satellite, traveling with the cloud.” In Massachusetts, an amateur astronomer watched the plume perform two full turns in four minutes, painting the spinning spiral as he watched.
In the United States and Canada, observers had witnessed a spray of surplus fuel from the used-up third stage of the Japanese rocket. Their altitude was almost a thousand miles (1,500 km), high enough for it to have been sunlit even though the ground below had been dark for more than an hour.

I wonder why the OP hasn't been back. Hit and runs bug me.

That's a nice piece of work but there could be a problem with your initial assumptions (and a few other things). Based on a single photograph, you have assumed that the size of the spiral in the distance is proportionate with the size of the objects nearer to the camera. Depending on the lens used, this is not necessarily the case. Perhaps you could expand your thesis to include an analysis of these images:

I can't believe I have to post this again. So far every single expert in the field has said it was a failed missile. Those on here who think it's something else are like people thousands of years ago pointing at the sun and saying it's a god because they simply don't understand. I've had enough with being polite on this matter - people spewing this 'it's not a missile' drivel are making ATS look ridiculous. The evidence for it being a missile is everywhere, from the shipping warnings, to the clearly-visible exhaust plume extending all the way down to the horizon, to the two spirals caused by the fuel leaking, and the fuel being burned.
It's preposterous to claim it's anything else. Poor trigonometry isn't going to change that.

In your earlier attempt your trigonometry was in error so you really demonstrated nothing. But the OP of this thread had an interesting idea to use the radial velocity of the effluent to prove that the source of the spiral could not have been the Bulava. Let's revisit this idea but clear up some problems with the OP's attempt.

trigNspirals, could you tell me what your qualifications are?
is this your field of study?
or profession?

The diameter of the spiral has been described by eyewitnesses as being 2-3 times the diameter of a full Moon.

QueenAnnie,
I am a physics undergrad at UIC, taking some grad classes and awaiting admission to grad school for physics.

i meant to address this earlier, that you said also in another post.
when the moon first rises over the horizon, it can, depending upon the setting and surroundings of both the horizon as well as the observer, appear to be far larger, proportionately, than it should be.
and then, as it continues to rise, it appears to "shrink" to a more familiar apparent size.
i'm sure that most of us, if not all, are familiar with this "optical illusion."
i'm not saying this in a direct reference to your facts and figures, because my brain deals with numbers in ways that are not of a mathematical nature. by that i mean that i could not even wade into the numbers in regard to the principle i described above - but i do feel sure that is a factor that must be considered, regardless, when using it as a "ruler," so to speak, in these calculations.
and we surely all also know how easy it is to miscalculate estimations of size and distance when we are observing something set apart from any sort of reference at all.
how can the moon be a reliable reference for observation, when it, itself, offers no reliable reference of its own when it is hanging in the sky?
When using a lens with a narrower field of view, a telephoto lens, the image needs to be stretched to fit the space, as shown in figure 2(c). The perspective is again distorted, but in the opposite way. Scale and distance proportions between foreground and background diminish so that objects far away appear larger than they are and nearly as big as those close by, and it appears there is virtually no distance between them.

Do you think the optical illusion is an intrinsic property of the moon?

Careful Queenannie or the FARRTs will try and convince you the moon is made of green cheese !
