2 objects near Nashville airport.

I was down Murfreesboro Rd going under the runway by airport.  When i came out from under it I seen 2 bright lights with some dimmer lights above it.  They were really low in the sky.  It was 2 of them because they were moving in different directions. It looked almost like parachutes because of the way but it was dark so I couldnt see anything else.  As i watched them move away from the airport headed east one got dimmer.  I lost them in a back road but when i turned onto smith springs rd i seen them again. They were higher in the sky.  Then i seen one of them just shoot off going Very very fast in the sky.  I lost the other one.
