Absolutely outstanding shot! This was one of those images while screening that made me stare at the monitor for about a minute just thinking... Wow! Perfectly captured, perfectly timed, just outstanding. Thanks for sharing it!
And what a fantastic picture this is indeed! Highly deserved screeners choice, congrats. I visited Cape Canaveral earlier this year and while looking at platform 39 I wondered what it would be like to witness a Space Shuttle launch. This picture just answered my question ;o)
