Listening is a more natural way of learning, when compared to reading. Written language only began at around 3200 BC, but spoken language has existed long ago.

Learning by listening is a great way to:
- increases imagination and understanding
- improves your listening skills
- improves your own spoken accent
- learn while on the move
- reduce eye strain

Now learn the vast amount of general knowledge available on Wikipedia through audio (audio article). You could even learn subconsciously by playing the audio while you are sleeping! If you are planning to listen a lot, you could try using a bone conduction headphone, or a standard speaker instead of an earphone.

SUMMARY
=======
The Boeing KC-135 Stratotanker is a military aerial refueling aircraft. Both the KC-135 and the Boeing 707 airliner were developed from the Boeing 367-80 prototype. It is the predominant variant of the C-135 Stratolifter family of transport aircraft.  The KC-135 was the US Air Force's first jet-powered refueling tanker and replaced the KC-97 Stratofreighter.  The KC-135 was initially tasked with refueling strategic bombers, but was used extensively in the Vietnam War and later conflicts such as Operation Desert Storm to extend the range and endurance of US tactical fighters and bombers.
The KC-135 entered service with the United States Air Force (USAF) in 1957; it is one of six military fixed-wing aircraft with over 50 years of continuous service with its original operator.  The KC-135 is supplemented by the larger KC-10.  Studies have concluded that many of the aircraft could be flown until 2040, although maintenance costs have greatly increased. The KC-135 is to be partially replaced by the Boeing KC-46 Pegasus.
