[first lines]

William Adama: Dear Dad, in your last letter, you questioned whether it's my responsibility to join this fight. The truth is we all became responsible the day we created the Cylons. We're the ones who let these robots become our servants, our trusted helpers and even our friends. We let them into our lives, only to see them repay our trust with a violent revolt against us. I know there's a lot of debate about why they hate us. But in the end, does it really matter? Kill the enemy or be killed. That's a reality. In a war where mankind's very survival hangs in the balance, it's up to each of us to make a difference. Being a pilot is the best way I know how to do that. Your loving son, William Adama.
