Okay, so you're Luke Skywalker. As we all know, at the very last second and with the fate of the rebel alliance on his shoulders, he let's the force be with him and switches off his radar as he fires the torpedo down the shaft of the Death Star. A pretty ballsy move if you ask me, if only because if he missed, the planet would have been destroyed, the Death Star would still be in operation and only a rag-tag fleet of planes would be able to assemble somewhere else to continue on with the rebellion, their forces depleted. And if that all happened, Luke would then have to explain that the reason why he turned off the radar, or whatever that was, was because he heard the voice of a half-senile old man in his head telling him to trust his feelings.

I'm guessing that wouldn't go over very well.
