I had not seen the video posted above before, somehow missed it, but man we are so blessed on this planet to have some of the most miraculous looking
skies.
I will never tire of cloud threads and yes I even believe that they can and do at times cloak starcraft, so even though this one has been debunked,
please dont keep looking.
That is a cloud I have seen these from all different angles and altitudes, they normally form after a microburst, when there has been intense rain or
hail, in this instance, cumulus nimbus has a big hole in the bottom that it's trying to patch up, severe up draughts and down draughts, have caused
many aircraft incidents, some fatal.
How long have I been surfing the net.
The lenticular cloud UFO.
I must have seen that posted a dozen times.
The one I found with the dark cloud at the end is on a Channel
with a lot of CGI and in the second one only a few look like
the normal dark or bright objects in the sky.
