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
=======
This article lists the flights of the North American X-15, an experimental American spaceplane built by North American Aviation and operated by the United States Air Force and NASA.  From 1959-1968, twelve pilots flew three X-15 planes, flying record high-altitude flights, high-speed flights, and sub-orbital spaceflights.  Collectively, pilots and craft performed a total of 199 free flights after being carried aloft and then air launched from one of two modified B-52 mother ships.  The pilots and craft also performed twelve scheduled captive carry test flights and 125 aborted flights (frequently due either to technical problems or poor weather) in which the X-15 did not uncouple from its B-52 mother ship, for a grand total of 336 flights.  The X-15 program's flights generated data and flight experience which supported future development of aircraft, spacecraft, and human spaceflight.
Five principal aircraft were used during the X-15 program: three X-15 planes and two modified "nonstandard" NB-52 bomber carriers:

X-15-1 – 56-6670,
X-15-2 (later modified to become the X-15A-2) – 56-6671,
X-15-3 – 56-6672,
NB-52A – 52-003 nicknamed The High and Mighty One,
NB-52B – 52-008 nicknamed The Challenger, later Balls 8.Additionally, F-100, F-104 and F5D chase aircraft and C-130 and C-47 transports supported the program.
