It was a jet airliner flying in from Hawaii

I am an aerospace engineer who helped to launch dozens of rockets from Vandenberg AFB, Titan and MX. I have also watched at least 100 rockets launched from Vandenberg during the 30 years I lived near there. It's way too slow to be a missile, and there is no white hot rocket flame continuously shooting out, here is a real missile launch:

Notice the missile only lasts three minutes, not like the airliner off LA which was filmed for over 10 minutes, because a missile flies ten times faster than an airliner and burns it's fuel out in those three minutes.

Also the contrail is wrong, after a few minutes a missile contrail looks like this: http://en.wikipedia.org/wiki/Twilight_phenomena.
I have seen many of these missile contrails at sunset.

Stop wasting your time on this, instead start calling politicians tomorrow and tell them no Dream Act ever, we want the SAVE Act!! That is the real conspiracy right there, not this airliner mistaken by non-experts for a missile.
