content: I came across this when doing weather modification research:  A hurricane hunter aircraft on loan from the National Oceanic and Atmospheric Administration also pitched in. "One of their two (hurricane hunting) aircraft came to North Dakota and flew on our project," Boe said, adding that the hurricane researchers told him the North Dakota storms they encountered were rougher than any hurricane they could imagine. One "nasty, nasty" storm from late June 1989 still stands out for Boe. "We all agreed it was rough, even by our standards," he said.  Sauce
