The NCAR team spent the next ten years working on the problem with researchers at airlines, universities, the F.A.A., NASA, and NOAA—the National Oceanic and Atmospheric Administration. “It was a national imperative,” Cornman said. Luckily, the beginnings of a solution were already in place. The team at NCAR had used sophisticated new Doppler radar systems to detect microbursts. When those were added to the wind detectors already installed at many airports, and the two systems were integrated with software that Cornman developed, microbursts could be detected as they were happening. “A problem where hundreds of people were dying suddenly stopped,” Cornman said. The last time a commercial flight was downed by a microburst in the U.S. was in 1994.
