I understand seeking the thrill, experiencing something that few people get to experience, be there, see that, do that, etc. and that sometimes the thrill seeking can be deadly, but is it true that the submersible had no windows, and that the passengers looked at the wreck throw an outside camera and a monitor inside the sub? The passengers could've been watching previously shot footage and never know it.
No, it had a small porthole at the front. That was only certified to 1500m and not 4000m, if what I remember reading about the complaints of the director of engineering they sacked a few years ago is right.
