Quite possibly the coolest thing ever!

I saw the coolest thing ever a few nights ago. On February 10, 2011 at approximately 6:00 pm EST, I saw a fireball. No, I take that back...I saw two fireballs and the remaining smoke trails of two others. I saw the very end of one and the entire streak of another...it was incredible!! The fireball itself was a red/yellow color and the trail it was leaving was white at first, then it changed to black after about 5 minutes or so. It was a VERY slow moving object, and it went alllll the way down to the horizon as far as I could see. I didn't see or hear anything about it and I didn't have the internet working until today so I couldn't really search to see if anyone talked about it...so far I have found nothing! It's crazy! I took my husband outside about an hour later and the smoke trails, very much still intact, were literally at my zenith. It was just incredible!!! I'm looking for a picture but I can't find one...I was so mesmerized by what I was seeing that I didn't even think to take a picture but I saw several planes flying around so SOMEONE knows what it's about...
