I run forever, With a roaring call. Yet I have no throat, Or any legs at all. Rock wears away, Whilst I grow. You try to race me, And receive a blow. What am I?
Sometimes I am loved, Usually by the young. Other times I am dreaded, Mostly by the old ones. I am hard to remember, Also hard to forget. And yet if you do, You'll make someone upset. I occur every day Everyone has to face me. Even if you don't want it To happen; embrace me. What am I?

Wireless telephone at White House

In 1919, President Wilson used a radio telephone set up on the south portico of the White House to direct the maneuvers of a dozen army airplanes flying over the Potomac river several miles away. His telephoned directions went direct to the flight commander in the air. The instrument was similar to those used by American aviators in France in the latter part of World War I. Col. C. C. Culver actively developed the equipment. He began the project in Aug 1910. No new invention was needed, only adaptation and adjustment of existing techniques. By Aug 1916, he was able to send a radio telegraph signal from a plane. Enlisting expert help from the telephone companies, by Oct 1917, voice messages could be send between a plane and the ground. The system was put into service for military wartime use.«
