Crash Landing Object.html



A crash landing can be an aviation accident. Also meteoroids collide with the Earth and other celestial bodies. A large collision is called an impact event.

Planned crash landing

In the case of landing unmanned spacecraft and parts such as a rocket stage or fuel tank, a crash landing may be intentional. This can be a matter of disposing of such an item, or a way to photograph a celestial body from nearby without providing for a soft landing, or the impact may have a purpose by itself, such as with Deep Impact (space mission). Also the third stage of the Saturn V rockethttp://en.wikipedia.org/en/Saturn_V#S-IVB_sequence was deliberately crashed into the Moon for seismic measurements.
