Well , Mig-19 could take-off with without airstrip ,as we can see from video below . Landing was out of the question , but even VTOL aircraft need big ship (i.e. helicopter carrier at least) to land . At the time when J-6 was relatively modern China didn't have anything bigger then destroyer , so even true VTOL aircraft could not be used . On the other hand , onboard J-6 could be useful in some circumstances providing there is enough fuel to safely land on (J-6 has relativity short range)

that is one brave Russian test pilot!
50 years ago there is no computer simulation. If you're the first guy up there, it's most likely also the first time it's done! I seriously doubt they were shooting pilotless rocket Mig-19s over the rails a few times over just to be sure it works...
