新雷达防止小鸟撞飞机

"Here we have a flock of birds that's moving to the northeast."

It's been one year since the "Miracle on the Hudson", as we all now know just a few small birds can bring down an airplane. And now, at the international sea airport in Seattle, Washington, a new radar has been installed that gives pilots an early warning.

"We can bring it into our vehicle and we can see the bird hazards real time. Actually, when they are happening."

The system records and saves birds' flight patterns hour by hour and allows researchers to develop wildlife forecast, much like weather forecasts.

"Where the accident of 1549 occured was right at the outer reaches of where this radar is currently sampling today. And the question comes up, even if we did or were able to detect those birds at that elevation, can you really get specific enough instructions to the pilot?"
