No, I'm just addressed the analogy of jet airplanes and pointing out those are tightly controlled. I understand that current rocked are very tightly controlled, my point is just that any sort of interstellar rocket would be much more dangerous and thus have to be subject to much higher controls. A ship that was capable of reaching a significant fraction of light speed would be the most dangerous weapon ever created though, and existing controls might not be sufficient.
