There is nothing wrong with this comment. The objections he raises are perfectly valid. Yes, it could have gone dreadfully wrong. In this instance, it didn't, and it is a credit to the engineer's skill that it worked. For many other people however, it would definitely be a bad idea to try. Yes, it's great that he did it, and that he took fast action to save a life. It really is; it's a great story! But a down-to-earth comment is not worth downmodding over; it is neither wrong nor irrelevant.
