I was at port canaveral last night to see the launch. Was dissapointed for the scrub but it was a fantastic sunset. That’s the way it goes sometimes.

I used to live in Florida. I have seen launches from Saturn V through Space Shuttle. Skipped college at UF to see the first Shuttle launch. Have seen night Shuttle launches from the VIP viewing area. Sadly saw the Challenger disaster. Have also seen DSP and Milstar satellite launches.
