What did Lonnie Zamora see??

There are a few things about this case that don't seem to be in question.
1. Lonnie Zamora is of the highest caliber of witness. He was a police officer, rather quiet, and performed his job well. To nearly all investigators, his credibility is impeccable.
2. Lonnie Zamora saw something. Taking into account his credibility and the evidence left behind, it has become increasinly clear that, indeed, the incident did happen as Zamora described.

The first two videos give a synopsis of the case.

Zamora Part 1

Zamora Part 2

This last video has three parts. One attempts to explain what might have been seen by looking into technologies that were being tested at the time the sighting occurred. The next part of the video shows clips from principal investigators including Hynek. And some classic Rod Serling as well. The last part includes excerps from Unsolved Mysteries seen in the above two videos.


I can't say what he might have seen. A lunar module seems unlikely given the morphology of craft described and sketched. A very interesting case indeed. Especially interesting is the sound and propulsion. At least when the craft lifted off the ground. After that, Zamora describes the sound stopping. Apparently complete silence. So, while I look further into this, my questions:

1. If it were a lunar lander wouldn't the sound be continuous??
2. By this time, couldn't we measure the dimensions of lunar landers or other known craft being tested and compare them with the landing feet dimensions of the Zamora craft?
3. Was such known craft operated with and tested with two people??
