Hurricane Hunters from the National Hurricane Center use the C-130 Hercules, a very sturdy turboprop place.  It's not beefed up in any way, only the special weather equipment makes the WC-130 different from the cargo version. The crew has six members: two pilots, a navigator, flight engineeer and two weather specialists. There are ten aircraft to cover up to five storm missions per day, anywhere from the mid-Atlantic to Hawaii. http://www.hurricanehunters.com/photo.htm.
