There is evidence that they were just north of the main circulation, which is a very stupid move when it comes to chasing. There was also evidence they were core-punching, which is also moronic. This has not official news. This is gathered from where I heard they were when it happened, relative to the storm's location. I'm glad he's okay, but that was irresponsible of the team if this turns out to be true.
Stay south of the storm, and don't core punch. With a storm as violent as this one, give it several miles of berth. Getting right up on a circulation like this one is just asking for trouble.
