AS PROMISED IN #220:

---

While we were working together on another thread, Rokke challenged me to determine the viewpoint and azimuth from which the CBS helicopter made this video frame:

So - I downloaded Google Earth, gave it a try, and here is the result:

Recently, I noticed that a frame from one of Mick West's "Google Earth Movies" nearly matched the video frame's viewpoint -- so I added my azimuth to it:

Compare it with the top VidFrame, and you will see that it matches perfectly -- and it puts the contrail in the video frame precisely on the flight path for UPS 902.

Folks, one of the basic principles of the scientific method is independent verification of results.

You have just witnessed independent verification!

This verification gives me high confidence in the accuracy of this (North-south referenced) azimuth to the contrail very late in its lifetime.

Furthermore, it convinces me that, if we wanted to expend the effort, we could produce a master map of the coastline and nearby ocean, with azimuth vectors from every recorded viewpoint pointing to the position of every image of the contrail -- as it both grew eastward and drifted southward.

AND, we could add in the azimuth for the sun's position -- which should totally destroy the "shadowing" foolishness.

THE QUESTION: Is that more-detailed presentation worth the effort?

MY ANSWER: As sound as our case already is -- probably not -- except for the exercise (and fun) of doing it...

Thank you.

Remember, every year the Nile flooded, and from the time of first settlement until the construction of the Aswan High Dam, it was necessary to RESURVEY the open country used for farming every single time.

The earliest stone age Pharoahs did so with minimal tools and without geometry or a decimal counting system.

They used TRIGONOMETRY. Having once been a math major I had my Euclidian geometry, solid geometry, calculus and TRIG down tight ~ I enjoyed this opportunity to refresh my memory of HOW TO DO IT.

Excellent.

Not that it will make a dent in the impervious and insatiable desire of the "missileers" for it to be something launched by the Chinese.....

“AND, we could add in the azimuth for the sun's position — which should totally destroy the “shadowing” foolishness.”

What shadowing foolishness?

[ex 98C MI Dude]

Excellent work, but I fear it is all for naught. Some people are just determined to believe that this was a missile launch, and no amount of proof will convince them otherwise.

But your post means you are a member of the vast conspiracy to protect Dr Evil’s diabolical missile from discovery!/s

Applause for post #229

Kudos.

Well done!

Your first two photos helped me understand something Gil Leyvas stated when we spoke. He said there were details in the video that had not been shown on TV or online, such as how at one point the contrail lined up parallel with the LA harbor jetty, which was how he was certain of the location of the contrail when he first spotted it. I don’t think that first image you posted was in any of the video I’ve seen online. I had reviewed some images of the LA harbor but never understood this perspective of the contrail being parallel with the harbor jetty till you posted these two images.

I extended your plotted line of site from the Leyvas video to the approximate location of the UPS902 flight path. Not surprisingly, it intersects almost exactly the lat/long of where Flightaware says UPS902 was at 5:15.

I'll go through the steps I took below and I invite anyone to follow the same steps and identify anything I've done that isn't accurate based on known data...

1. We know exactly when the Cargo Law photo was taken, and where the camera is located and the direction it was pointed when it took the photo.

2. We know exactly where UPS902 at each minute based on the data from Flightaware. Flightaware UPS902

3. It is possible to plot the lat/long of UPS902 at when the Cargo Law camera took its photo.

4. Plotting the line of sight from the Cargo Law camera at the time of the Cargo Law contrail photo was taken crosses the flightpath of UPS902 at almost exactly the lat/long of the aircraft for that time as recorded on Flightaware.See this post

Therefore, it is safe and logical to conclude that the Cargo Law camera took a photo of the UPS902 contrail.

Now, lets take a look at the Leyvas video, and specifically a still from the video that shows Long Beach harbor.

We don't know the exact time the video was taken, but we do know it was sometime around 5:15. Plotting a line of site from the helicopter toward the contrail in his video provides the following (The red line of site is from the Leyvas helicopter and the yellow is from the Cargo Law camera).

Not surprisingly, the line of site from the Cargo Law camera toward UPS902, and the line of site from the Leyvas video intersect at very nearly the same point. Therefore, it is safe and logical to conclude that the contrail in the Leyvas video is the same contrail photographed by the Cargo Law camera. And since we already know the Cargo Law camera photographed UPS902, we now also know Leyvas did too.

Again, thank you so very much for sharing your insights, dear brother in Christ!
