Is this possible?

No. It is not possible for the plane to kill off its survivors because they have already survived the crash. There are no other things that can kill the survivors anymore. If the question stated passengers, then the answer will be different.

It is important for people to always take note of the terms and words that are used to construct sentences. It will help people understand what they have to look for. Another thing that should be noted is the fact that no bodies were recovered. It is likely that all of the passengers survived and they walked from the crash site or they were already rescued.
