RIP, Phil. He was a cool guy to watch.
Since they were offloading during the middle of Opie season, I would say they almost certainly have footage of his initial issue. Not sure if they will run it though since his death. They did show his last problems when they happened, but of course, he made it out OK.
They are in a difficult spot. On one hand, the whole point of the show is it is a dangerous job and they risk their lives. They have shown us other people who almost died or were dead (though they of course blurred the bodies). They have shown the captains worrying about others who might be lost while listening to radio calls. They showed the poignant tapes of the crew that died after filming them. Of course, none of those were main characters.
On the other hand, in future seasons, how the Harris Brothers and the rest of the crew responds could be very interesting and instructive for those who have followed this show since the beginning. Hopefully they all make it through OK as dozens of people depend on that boat for a living.
