What a cool perspective!
Indeed he even says
'not half as nice as the view was out the window'

Keep an eye out for the flashes of lightning
in the dark lower atmosphere region under the NLC's.



Also the 'bright star' he talks of methinks was Venus maybe?

I mentioned 'gravity waves' (atmospheric) before and
how much like them these NLC's look every now and again...
The same principles for the formation of both may be connected?

Very cool, although I wouldnt involve gravity waves in their formation, more like they resemble some sort of surface waves between 2 different density layers.
I dont see how gravity waves (ripples in space time) could be involved.

Very nice frank you could say they have a room with a view.

Dave I think Frank is referring to this en.wikipedia.org/wiki/Gravity_wave

Wow now thats cool.

oh right, so "gravity waves" can mean 2 completely different things, never heard of this referance before.

Yup Dave,
although I did say it to you a few times
I was fairly sure you didn't get what I ment.

Anyway Ya,
It's just I was searching on the net for NLC's
and came across this vid on Utube with the tag 'gravity wave'
(the atmospheric / cloud kind )
eg




I just have seen a few images of these high cloud gravity waves
from space and thought they really do look
like the ripples that are so distinctive in NLC's..
