[Star Wars] How could the Rebel Alliance allow an untrained pilot to partake in one of the most important battles of the civil war? 

This question is in reference to the first Death Star battle. How could the Rebel Alliance allow Luke Skywalker, an untrained pilot, to fight in the battle against the Death Star? 

Think about it. Here's quite possibly the most important battle of their entire campaign, and they're allowing a newbie to fly an X-Wing. How did they know he could fly it? Or, that he wasn't a spy? Wouldn't they have wanted their best pilots for the task, and couldn't Luke have really screwed things up if they were wrong about him?

Because there is is no such thing as formal training for terrorists. A pathetic criminal organisation such as the rebel alliance will make use of any yahoo who claims to have the ability to use a gun regardless of the risk or the conveniences. It was luck that Skywalker was as good as he claimed to be, as many of his compatriots weren't.
