Illuminated object appeared and streaked across sky

Traveling northbound to titusville from cocoa when directly in front of our vehicle a very large brightly lit object just appeared in front of out car and at the most outrageous speed streaked halfway across the horizon drom east to west and disappeared . As if it "blinked on" in front of us and stayed illuminated while it Traveling lateral for about 1 second then "blinked off" and disappeared. I looked over at the driver and we both screamed what the hell was as that? We had no obstruction in our view no clouds or trees it was a clear nice night and was plainly clear. There were no other vehicles on the road around me at the time or I would have flagged them down it was the most clear airing I could imagine. I called my husband and our family when this happened and he found this report center for me to document this. We live on the space coast and regularly see rockets, shuttles, aircraft from the space center to Patrick AFB and this was NOT fireworks, comet,shooting star or anything like that. It was huge! I can't say the size except this was no airplane this was a large object extremely bright in a color o can't even describe. Blueish white green. It appeared and I thought... what is ... and before I could even process the thought it shot across the sky and was gone..... absolutely incredible to see. Thank you
