The data is transmitted to the American hurricane research center in Miami, increasing the accuracy of hurricane trajectory and intensity forecasts by 20–30 percent. Flights last ~11 hours, with enough fuel for four passes through the storm's center. The crew spends 10–20 minutes in the eye. #HurricaneResearch #WeatherForecasting #FlightDuration #EyeOfTheHurricane
