White light with blinking red light and helicopter sound following it

Tonight, while walking my dog, I witnessed a white light, like a plane, moving across the sky (west to east) with a blinking red light and helicopter sound following it.  I continued to watch both objects as I thought they were both from XNA.  However, when I saw the red blinking light catch up with the solid white light and it seemed to chase it away, it seemed odd to me.  There was never a plane sound, there were no green and red lights attached to the white light and there was only the sound of a helicopter.  Yet, the white light disappeared in the distance after the blinking red light and helicopter sound caught up with it.
