EVERY time they launch, it's cloudy here in Jacksonville! I will always say the very best launch I witnessed from here was Columbia, in Jan 1986 (The launch before Challenger) It was at around 8-9 PM, it was crisp, cool and EXTREMELY clear. I mean zero haze! It was also a rare launch that went in a more NE direction. I remember I could HEAR it from my roof top and clearly see the Boosters break away. My Dad used to tell me the Apollo Saturn Vs were VERY impressive from Jacksonville.
