Unless you actually know that, you don't actually know that. After all, it's not like such a thing would be admitted. Not even Obama could ignore the reaction if this was a Chinese or Russian launch.
And... the military is claiming LA ocean airspace for days more after "their" launch is supposedly over. Which doesn't make sense, unless they're tracking someone else...
Unless you actually know that it was a chinese missile, then you don't know that either.
The missile plume alone last night at one time covered 1/3 of the horizon in a bright exhaust plume that was spherical and typical of high altitude phenomena associated with missile launches. The supposed missile you are talking about never exhibited any characteristics remotely similar to last night's display.
I was part of the team that launched Minuteman ICBM FOTE shots in the late 70's and 80's from Vandenberg AFB. I have launched my share some that exhibit the "twilight phenomenon".
The phone calls and questions from the public and the "learned press" we had to answer after every such event would stupify you. They only proved why we , as a country, post so low in worldwide science scores for our high schoolers.
It was a UPS cargo flight. They even have the flight #. Unless you listen to Alex Jones, that is . . . .
You should come visit Albuquerque. We get images like the one that was claimed to be a missile a few years back almost on a daily basis. Wide open skies, and contrails, combined with high-altitude winds make for some pretty cool trails in the sky.
I have my doubts that the sighting a few years ago was a missile, but I don't know for certain. All I can compare it to is what I see where I live. And I'm constantly seeing things in the sky here that look like what that did a few years back. I've has some west-bound jets coming over the Sandia Mountains at us (I live west of them) that look exactly like missile launches. The major difference here is that you can watch the aircraft progress across the sky.
