Science: Voices from Heaven

The attempt to radiocast a diver's voice from the seabottom having been successfully carried out in Philadelphia (TIME, Aug. 11), the Radio Corporation of America last week radiocasted the voice of an aeronaut, a mile above the earth.

An Army airplane from Mitchell Field, L. I., flew above Central Park, Manhattan. The airplane carried a sending and receiving set and a similar set was erected in the park beneath. An officer in the sky then chatted with an officer on the ground. The receiving station on the ground amplified the aeronaut's words and the entire conversation of both men was sent by wire to the radio casting station of WJZ in Aeolian Hall, three miles away, and there put again on the air for radio fans to hear.
