That was very strange - at one point I saw four separate point sources of flame. I said to myself, G-D, I hope that was staging. The first stage seemed to climb after the second for quite a ways. Then there were two additional points of flame that seemed to come off the second stage. Strap ons? Didn’t think that configuration had those.
The first stage will climb a bit even after staging. What you saw up there I don’t know.
