A slightly neater illustration of the converging (in 2D) essentially parallel (in 3D) rays
And on lighter note, here's me from a few years ago illustrating how shadows change in 2D as your position changes.
Everyone is kind of correct. The problem (not really an important or useful one) is one of precision in terminology. 3D vs. 2D, line segments (between two points) vs. rays (hypothetical projection of a line segment to infinity).
Lines that are...
It's just another example of the tired old argument based on the misunderstanding (or willful misunderstanding) about parallel sunrays and perspective.
There's the Apollo Hoax argument about more than one light source on a soundstage:
Discussion on an Ag forum:
Most around here have the strobes on the pivot to let you know the machine is still walking. It's a nice feature since you don't have to go to the pivot and make sure it is still operating correctly. Some have the end...
Looks like "Keith Foster" (keithfoster8021) beat me to it, a comment on this video.

Every single center pivot irrigation system in southwest Kansas has strobe lights flashing on them while they are watering crops. These...
A possibility is center pivot lights on irrigation systems. Basically warning lights to show the large circular irrigation systems are moving
Here's one filmed from a mile away.
For the air data, see the first line here:
Through the video the degrees for lat and lon are always 31° and 111°, so the "Raw-Latitude" and "Raw-Longitude" omit them. Coincidentally the first minutes value is also 31, which is a...
I have taken the Data points in Appendix E of the SCU report and plotted the data in 3d using Google Earth in a similar style to Figure A8..

On page 5, Reali says:
The object is tracked by an airplane and appears to be moving at a velocity against the wind as described one of the pilots in Appendix F Sec. 6 (p. 46). The plane is circling the object at 157...
They do give a link to a HD version of part 2 of the video:
Which might be useful if someone ever wants to play with automated screen scraping of coordinates, or suchlink...
More bad (or, at the very least, entirely unclear) reasoning:
Reali, page 42:
In Fig. A8 (p. 17) and Fig. E2 (below), the green line shows a possible trajectory of the object as the plane tracks it in its circular path. The yellow points RV1, RV5...
