As a matter of luck I discovered its presence. I took the daughter and drove over to see it.
As a further matter of luck, I discovered from some passersby that it was scheduled to leave at 1pm. We got there about noon. So, we grabbed a bite to eat and then came back to tail gate!
About twenty minute before one, they started the APU, which was remarkable loud, then, after that had stabilized, about ten minutes later they began start up procedures. That blue smoke is from the APU start if I remember right.
They ran the engines up once to a towering crescendo and then dropped the throttles again. Then finally, with the entire crew, which, if my count was correct, was five, the crew door forward was closed, throttles ran up again and breaks released and it moved out.
It rotated outside of my vision. I was hoping for more of a vertical lift off, but alas it was not to be.
Still, for a Saturday afternoon around here, it was great excitement!!
