2nd flight just a few minutes after the first.  For this flight, inserted a C6-7 that was manufactured and purchased approximately 30 years ago!  Just like the first flight, this 2nd launch was nominal... However, this flight achieved a significantly higher altitude than on the new C6-5 a few minutes earlier.  Duration of this flight was approximately 50 seconds, and the rocket landed approximately 150 yards downwind from the launch site, narrowly avoiding a tree.  It will fly again another day!
