Ida Nelson was in her sister's sauna (桑拿浴室), relaxing. Then she heard the long low sound of a small airplane 1 the nearby airport.

It was 11:30 at night in the 2 of Igiugig, population 70, and, as she told the New York Times, "Any time a plane flies over that 3, you know something is 4."

Nelson and her sister leaped out of the sauna, ran to the window, and 5 the problem: The airport's runway lights were 6.

Nelson 7 on some clothes, jumped into her car and 8 it to the airport, where she found a local pilot trying to turn on the lights by hand.

"9, if you push the button 10 or 15 times, the lights will just light up," Nelson said. Not this time. Meanwhile, she and the pilot learned of the plane's 10 task: It was there to transport a seriously ill local girl to the nearest 11, 280 miles away in Anchorage.

Nelson had a 12. Driving her car to the end of the runway, she 13 her headlights (车头灯) on the road for the plane to follow. Great idea, but it wasn't 14. More light was needed, so a neighbor called nearly every home in the village — 32 of them.

Within 20 minutes, 20 15 arrived at the airport. Following directions from the plane pilot, the cars 16 up on one side of the runway.

The plane made its final 17 and, guided by the headlights, landed safely. The young patient was loaded onto the aircraft, and the plane 18 took off again.

In a world filled with uncertainty, the little 19 positive activism was a big deal. Not so much for Nelson. As she told CNN, in Igiugig, coming together "is kind of a 20 deal."
