Bane never crashed the plane with no survivors.
If we follow xenon's way of thinking:
Earth is moving (location a)
Plane is moving towards earth
When plane reaches earths original point (a) earth is somewhere else (point b) since it's moving. When plane reaches point b earth is now on point c. And so on. As you see crashing a plane is impossible.
If we follow Heraclitus's way of thinking:
The existence we sense is the balance of opposites and opposites can not exist without each other. That makes it imposibble for Bane to destroying CIA without destroying himself too. And that would shatter the existence we live.
