I think most likely the effect of military munitions on a civilian aircraft would indicate immediate death.
Probably not. The SA-17 has a 62kg warhead that's designed for a proximity detonation and pepper the target with fragmented pieces of the missile. People sitting near where the warhead exploded may have been killed by the actual detonation, but the blast radius of a 62kg is rather limited and those more then a few feet away and out of the range of the fragments would have survived the initial explosion.
