I witnessed 7 lights moving at a very high rate of speed going North West across the sky

On 3/15/15, at 1:30am, Over Cherry Hill, NJ, I walked outside my front door, like I usually do on clear nights.  I looked up at the stars.  When I looked up I noticed what looked like the stars were moving.  They were very bright, brighter than anything else in the sky.  There were 7 lights in a line.  
As they passed over at a very high rate of speed, and I know they were moving fast because when I watched planes fly over that are very high up and look very small, they move what looks like so slow across the sky. These lights were going 20x's faster.  They made absolutely no sound.  This was Early in the morning, no cars were outside and you could hear a pin drop.  The lights started crossing each others paths, then 3 split off and started moving west while the others went north west but just as they went out of site the three came back.  
It was very fast, I would say about 45seconds and they were gone.
