بیست و یکم - استفاده از کلمات ۲

Hello, again! Welcome to Words in Use 2 for lesson 21. “Safety in the Air”

The most persistent* plea* of weary* pilots, has always been for a machine that would warn them that they were about to collide* with an oncoming airplane. Studies of landing patterns confirm* that the number of collisions is increasing each year, and pilots verify* hundreds of reports of near misses. Recently a system that would electronically anticipate* oncoming airplanes was devised, and the pilot’s dilemma to dive or to climb, to detour* to left or right, may be solved. The system has merit, though, only if every plane is equipped to transmit and receive a signal to and from an oncoming plane. But most aviation experts feel that only a system that watches every airplane in the sky will relieve* a problem that tends to baffle* everyone who attempts to find a solution.

Our story is finished. See you in the next part, good luck.
