UFOs and G-forces, - and the 1947 flying saucer-wave again:

Regarding G-forces:

How can people (with known technology) survive the extraordinary acceleration and abrupt maneuvers UFOs often been observed to exercise - which in some cases suggest at least 100 times the G-forces? Most people begin to lose consciousness when approaching 10 to 12 G. ..

This is often mentioned as a "proof" that UFOs must be extraterrestrial, which I disagree on. One accepts that aliens are able to solve the problem of G-forces, but consider it impossible for us?
Besides, it can just as well be remote controlled, unmanned crafts that carries out the "worst" maneuvers?

My main point is that UFOs in 1947, according to the majority of the testimonys as they are reproduced in books that deal with the 47-wave, generally did not perform maneuvers that suggest that such forces were involved.

Claims of great maneuverability came later.

Maybe it's due to:

1: Escalation in the eagerness to describe UFOs incredible maneuverability from 1947 to the present.
2: A technological evolution.

Probably a combination, but I think option 2 is most likely.

During the wave of 1947, UFOs did not perform these fantastic maneuvers. It was reported amazing maneuverability compared to contemporary aircraft technology, but not so exotic that it must represent something extraterrestrial.

ET was obviously not in the mind of the general Schulgen, nor mentioned in any of the earliest documents concerning UFOs by the U.S. Air Force - this came later.

Schulgens memorandum, however, is full of references to German technology and research conducted in Germany during the war and in the years ahead of the war.

This tells me that what was observed in 1947, "looked all too familiar" two years after the war ended.

This is especially due to Nazi research on the boundary layer, as well as research on aircrafts with circular design.

Take a look at the document from 1936 I linked to in a previous post; - Wilhelm Kinner: "On wings with circular design" ("Über tragflügel mit kreisförmigen grundriss").

But what about sightings of aliens, some will surely object?

Regarding close encounters, meetings with aliens etc. I think it's important to keep in mind that most UFO sightings do not include observation of pilots / crew.

And in those cases when they are reported to not look like us, the "gray-aliens" and so on, it is important to check the source - reports can be manipulated, a manifestation of disinfo, etc.?

Ps! I do not reject the idea of ​​extraterrestrial life -, and I am not dismissive of that we may have had extraterrestrial visits once or several times in our history. Nevertheless, there are a number of facts that place the roots of the modern UFO phenomenon, that emerged in 1947, to Germany.
