The environment you fashion out of your thoughts, your beliefs, your ideals, your philosophy is the only climate you will ever live in. The key is in not spending time, but in investing it. ~Stephen R. Covey


1910 – The first public radio broadcast takes place; a live performance of the opera Cavalleria rusticana is sent out over the airwaves from the Metropolitan Opera House in New York, New York.

Birth of public radio broadcasting is credited to Lee de Forest. A 1907 Lee De Forest company advertisement said,

“It will soon be possible to distribute grand opera music from transmitters placed on the stage of the Metropolitan Opera House by a Radio Telephone station on the roof to almost any dwelling in Greater New York and vicinity… The same applies to large cities. Church music, lectures, etc., can be spread abroad by the Radio Telephone.”

In aircraft, an ejection seat (or ejector seat) is a system designed to rescue the pilot or other crew of an aircraft (usually military) in an emergency. In most designs, the seat is propelled out of the aircraft by an explosive charge or rocket motor, carrying the pilot with it. The concept of an ejectable escape crew capsule has also been tried. Once clear of the aircraft, the ejection seat deploys a parachute. Ejection seats are common on certain types of military aircraft.
