That close they had no need for survival gear. While the chance of a water landing is extremely rare here a PFD would be a good Idea. My survival vest is based on an old ALICE version with gear inside and out. I also made one for short kikes from an old BDU blouse. Not at all. I've seen the crashes and have concluded it would be foolish to put myself in a small aircraft. Just as it would be foolish to walk through a bad nieghborhood at night counting my cash.
