20+ bright red lights flying together over Bear, DE.

21:45 looking west watched approximately 20 bright red lights cross the sky over the course of 10-15 minutes.  Very bright, non-blinking lights in groups of 2-3 crossed the sky.  Did not hear any sound and did not see any color of light other than red.  Most appeared to fly about the same speed but saw one light "rush" to catch up to a group ahead of it.  They did not fly particularly fast except for the one that "caught up" to the others.  Speed was still not particularly fast.  I live close to New Castle airport so planes flying over are very common from small/medium jets to military aircraft from the Delaware Air Guard.  These lights were not like anything I have seen fly over before and they actually flew away from the direction of the airport.  
Also, had other aircraft flying by normally at the same time for comparison, these did not look like airplanes or helicopters at night.  I managed to take one picture with my phone, it is not particularly sharp but does show 4 of the lights in the right side of the frame and one more entering the left side.  I am emailing the picture.
We have written the witness, to request a copy of the photo, which we have not received, as of the date of posting the report.  PD
