Amazing that the BRS deployed and worked at that altitude, but a little reading revealed it's worked down to around 400' and can go even lower. Unfortunately a low wing aircraft hitting the top of something doesn't look good.
Although it may have nothing to do with this, it's amazing how many pilots I fly with just assume there is nothing in their way and turn without either dipping and looking, or lifting and looking. I try to tell them that one time, some day, you'll do that (lift/dip before the turn) and there will be an aircraft right there. It's happened to me.
