The Air Force Reserve's 53rd Weather Reconnaissance Squadron, known as the Hurricane Hunters, took this video from the center of Hurricane Harvey.The squad has been flying through Harvey since Aug. 17 to collect data for the National Hurricane Center. "The data we collect is essential to the NCH right now because the capabilities of satellites and drones is just not there yet," Maj. Kimberly Spusta, 53rd WRS ARWO, said before the storm hit the southeast coast of Texas late Friday. "To go into the center of the storm to get that data is critical so the NHC can have the most accurate forecasts possible."
