Yes all kidding aside as long as no one got hurt that is the main thing and we all can learn from it for the future.
Notch was off, back cut was wrong and the puller was in the wrong position to help in any way. Aside from that no one was hurt and that is by far the most important thing. Please be safe man, I'm sure you have people in your life that would never want to see anything bad happen to you, myself included.
