Wasn't there two guys somewhere in the caribbean, doing a study dive of something maybe and one was attacked by a shark - I remember the story sort of but can't remember where I seen it.......
Second post in this thread. There was a case where an oceanic whitetip attacked and killed a diver; notably the dive buddy was not attacked even though he was trying to drag the other diver to the surface. OW's are kind of an outlier; as a researcher once told me, "They don't miss meals." I've seen only one 5-ft juvenile and I was impressed with how bold she was. That said, she was certainly not frenzied - it took a while for her to appear and she would make a slow but determined run straight at us; once the safety diver pushed her away she would veer off, disappear into the distance, and then try again from another direction a few minutes later. The only other shark I ever feel like I've gotten that totally confident vibe from was a ~6-ft mako that seemed to know she could run me down at will if she decided to. Again, not frenzied but calculated.
Everyone can have a bad day, including sharks.
An object falling or rising quickly can indicate an injured animal and attract attention. I know from experience.
I don’t think the time interval is significant.
The descent rate, going by the report of 296 ft at four minutes into the dive, was about 1.2-1.25 ft/second - something that seems perfectly normal for a negative descent and nothing that I've ever seen a shark get fired up about. Usually when I see sharks amp up quickly, it's to a freediver who's trying to make the surface (possibly with a speared fish) in a matter of seconds. I've had sharks come and take a look at me on the way down with scuba, but it's always a look -> move away.
