High contrails can also shadow the clouds, making them darker and blending with the sky, like this

That, however, is not required to validate her claims. Her claims will be validated or not on Oct 14. If not validated, she will stand in line with
the thousands of false prophets that have plagued us over the past. In Moses time, they killed them for that. See Deu 18.
Let's say she's right. How does it fit into the Biblical prophecies and scientific evidences and forecasts?
The end times will have 7 years of tribulation, in the middle of which there will be something that changes things a lot. Hopefully, we won't be
here for the bad part. Look at the timeline:
Her spacecraft docks on Oct 14, 2008. They will be considered "sons of God" because they (1) came from heaven, or space and (2) have power over us
for life or death - the definition of god in the Old Testament (not to be confused with God, with the BIG G). Judges in the OT executed the laws and
punishments of God, so they were referred to as gods (even Jesus said so). If this is the case, then these sons of God will make bring back
conditions like in the days of Noah. See Genesis 6:1-2. These preconditions lead to the violence, and the return of Christ.
3 1/2 years from the Oct 14 date we are entering into dates around May 20, 2012 - the first solar eclipse of the year (visible in California, too).
Followed by a partial lunar eclipse on Jun 4. Again, both eclipses happen in Nov 2012.
This would fulfill "the sun shall be darkened, and the moon shall be as blood" in sequence (Acts 2:20). These would conveniently be mid-term before
the eventual date of 21-21-2012. The second 3 1/2 years the faithful will be raptured, hopefully. Who knows.
This stuff is rather ambiguous, just thought I would throw out some ideas on timelines. Not an exact science. Sorry.
