What happens to the helicopter as it lifts off at the end of the story?

"Kierzwinski thinks: I’m lifting, I’m lifting, we’re gonna make it. He sees the power line at the last possible moment. With the storm to his back he cannot climb any faster, and he cannot stop. He feels the impact before he hears it, and he knows he has hooked the power line with his skids. As Trooper 1 loses speed, time slows down. Kierzwinski pulls the stick with all his strength, hoping to break the line. The helicopter is temporarily suspended, roaring at full throttle but motionless in the sky. The radio comes to life."
