There are a number of things that can go wrong and cause a plane crash. Videos can sometimes help authorities to piece together what happened. Plane crash videos, coupled with other evidence, like the infamous ﾑblack box', are sometimes the best pieces of evidence to help explain what went wrong. Aviation officials will review the video(s), visit the crash site, and thoroughly and meticulously look at the debris left from a plane crash to determine the cause. Aviation crashes can be attributed to any number of things, including pilot error, mechanical failure, poor weather conditions, violation of FFA regulations, air traffic controller error, in-flight service negligence or a fueling error. Plane crash videos can also be used to aid in the schooling and training new pilots to help avoid such accidents in the future.
