I think from the plane's perspective they were far enough away, but from the ground the plane looked close enough to the rocket to make me scrunch up my face and try to do mental math involving a rocket traveling south on a vertical incline 100 degrees at 7.8 to 7.9 kms/s and a plane traveling north at 965 km/hr..... 👀 adjust for wind, carry the one, try not to have a small heart attack....
