It is 'zig-zag' in english as well ;-)

I am crossposting this to de.alt.ufo, a German UFO newsgroup.

Could you perhaps (in de.alt.ufo or alt.paranet.ufo) describe
a little bit more the light pattern, the manner of disappearance
(was it zig-zagging up and down, or left and right - or was it more
a rocking ('ruckend' in German) motion?

Yes no Problem, it had 3 Red Lights, one at each Corner, but i'm not
sure if there was a light in the middle (like on the Pictures from the
Belgian UFO Series). It disappeared with high (very high) acceleration
zig-zagging to the right to the left and again to the right
in approx. a 45 degree turning angle (it hovered for 1 or 2 seconds and then did this turns in a second or so and was gone...)

Was it disappearing out to sight because of its height or distance -
or both - or at what angle did it disappear?

While Zig-Zagging it gained also height. So I think it dissappeared because of the distance AND the height. The Angle where it disappered?
(I hope thats what you mean) Must be around 65 degree to the right and ca. 50 degree to the sky (i looked straight to east at this moment).

How big was it, please?

Hmm good question ;)

I guess it was hovering about us at ca. 150 Meters, and each side
of the triangle was about 200 Meters ... But if it was higher then
it could be even bigger.

I also have to say, that at this time i didn't submit this case to
mufon etc. because i simply don't knew that they exist at this time.
Since I got Internet i tought about submitting it, but i tought it would
be rather useless for them because i dunno the exact date anymore :/

You can answer in de.alt.ufo and I will post an update here myself
from your data.

[x] done ;)

Thanks!

I thank you, most people don't believe at such things and you earn sarcassm :/
