Two strange vapor trails and an exposion

A reddish blue streak like a vapor trail streaked across the sky going from N to S and suddenly terminated, like a comet that had burned up. Seconds later, in the same trajectory, very high in the sky, there was a small shower of white sparks like fireworks, and from this issued a white object the size of a large star. It slowly crossed the sky getting smaller until I couldn't see it anymore. It had a curious wide vapor trail that was fan shaped made up of billows of translucent white smoke or fog which could no longer be seen as the "star like object" got further away.
