Powerpoint Can Kill?
When a plane crashes, or even more rarely a spacecraft, the cause is seldom one thing. The systems they have catch and overcome single failures, or single human errors.
It usually takes a number of connecting events or failures to crash a plane or space shuttle, e.g. bad weather, a mechanical failure, plus a pilot error.

Edward Tufte is an information presentation expert - and his books are worth reading if you are interested.
