I live on the east side of Phoenix. Just be chance, about 15 years ago, I saw a launch from Vandenberg suddenly appear in front of me on and above the western horizon. It was dark in Phoenix at the time. Beautiful missile trail highlighted from behind by the sun setting over the Pacific. I mean, it was magnificent, majestic and powerful. Very large and wide trail.
I’ve been trying to catch another one all these years. I’ll be watching next Monday.
On closer reading. I think I may have got the wrong coast for tomorrow’s launch.
