OK, so people today fly airplanes into hurricanes to gather data. That much is understandable. But why would anyone fly into a hurricane before the Weather Bureau or the National Oceanic and Atmospheric Association (NOAA) ever existed to accept weather data?
"Just for fun," was the answer given by Col. Joe Duckworth [source: Coleman and McCloud]. He and Lt. Ralph O'Hair, both flyboys for the Army Air Corps were among the first people to fly an airplane into a hurricane. In July 1943, Duckworth and O'Hair flew a small AT-6 prop plane into the eye of a hurricane with 132 mph winds off the coast of Galveston, Texas [source: Old Farmer's Almanac]. While the pilot and navigator won highballs at the officer's club after safely returning that day, the prize for science was much more pronounced: The thermometers aboard the plane recorded a 25-degree Fahrenheit (14 degrees Celsius) difference in temperature between the eye of the hurricane and the air circling it.
Duckworth and O'Hair's flight into the Texas hurricane proved two things: It's possible to fly into hurricanes and survive, and such flights could provide valuable scientific information. Following that excursion, manned flights into some of nature's most severe storms became more frequent.
The next year, Navy and Army flights successfully tracked an Atlantic hurricane along the United States' Eastern seaboard. The coordinated flights reported on the hurricane's path and were credited with saving lives; a surprise storm had killed 600 people in New England six years before, while the 1944 storm (about which residents were forewarned) took only 50 lives [source: USA Today].
The advent of satellites in the 1960s made it virtually impossible for a hurricane to surprise anyone. Land-based researchers use satellite imaging to track the development and movement of every storm as it forms at sea. While these images provide information about the size and direction of a hurricane, there's still plenty of data associated with these meteorological phenomena that can't be culled from photos. Images provide overviews of a storm; to get the details, one must go inside.
Today, most manned flights into hurricanes are undertaken by the Air Force's 53rd Weather Reconnaissance Squadron (popularly called the Hurricane Hunters) and the NOAA. NOAA mans 8-hour flights into storms, going from one side into the eye, back into the storm and out the other side several times per flight [source: National Science Foundation]. NOAA drops a Dropwindsonde device into the storm to gather real-time data about the characteristics of a storm from top to bottom. The 53rd Weather Reconnaissance Squadron flies out of Keesler Air Force Base, Miss., and keeps track of Atlantic hurricanes with a flight crew operation of 20 people [source: 403rd].
Together, NOAA and the Air Force (and occasionally NASA) provide in situ (on location) data about hurricanes as they unfold. But the airplanes used by both groups have drawbacks. These are large, lumbering transport planes, like the C-130, and they don't fly quite as fast as necessary to provide the data needed to truly map the minute-to-minute changes in a hurricane [source: Henning]. The need for this kind of information still exists; until we fully understand all of the processes that create and direct a hurricane, we'll never be able to confidently model and predict future storms. With the advent of unmanned vehicles that can fly into hurricanes, it looks like this data will be provided without maverick humans flying into the storms.
