It was getting dark by the time the helicopter made its final approach.

How much difference 10, 20 or even 100 additional helicopters would make is uncertain.

The helicopter made an emergency landing on a baseball field.

Everyone ducked again as another helicopter made a low pass over the parking area.

Then, off in the distance, the helicopter made another turn.

It is believed that the helicopters made two or three trips.

It was about an hour before dusk when the helicopter made its approach to the huge military base.

The helicopter must have made an awful racket, but I didn't hear a sound.

And I was beginning to wonder if the helicopter could make it either.

But the helicopters make only four trips a day, for a total flying time of six or seven hours.
