This is how they realized where the aircraft crashed

Valuable information offered by the satellite Inmarsat 4F-1 and a method that was discovered in the 19th century, gave researchers of the missing Boeing the last position and an insight about where it crashed.

On Monday, authorities informed relatives of the victims on the bleak hope of finding their people alive and basically announced that all 239 passengers on board a Malaysia Airlines are dead. They proceeded to this assumption, without finding the wreckage of the aircraft. The obvious question that arises is how the researchers ultimately realized that the Boeing crashed "somewhere in the Indian Ocean". The response was given due to using the data of a British satellite company and due to Christian Doppler, who discovered the phenomenon that later was named after him. After the closure of the communication system, for which the expressed view is that it was deliberate from the pilots, the aircraft sent hourly pings to the satellite Inmarsat 4F-1 which is in orbit over the Indian Ocean.

The first conclusion is that the airplane continued to fly for hours after the last communication of the pilots with air traffic controllers. The second is that there were two possible paths that could be followed. One seemed to be directly south and the other directly north. Utilizing this information and the Doppler effect, which explains the changes in frequency and wavelength of a wave by an observer in relative motion to the source of waves (in this case the observer was the satellite), the head of the company concluded that the aircraft headed south. They even checked the data with the help of a second satellite, in order to offer safe updates on the survey results.

"New era for flight monitoring"

"We found one end to the state of Boeing, but the area which should be investigated, remains great" Steven Wood, CEO of the company All Source Analysis, said adding that it is relatively easy and not costly to monitor in a better way flight paths of aircrafts. "This accident could possibly change some data in monitoring aircrafts. And certainly, it will be for good, especially if we are talking about human lives" he said.

The first allowances and different data

Although the wreckage of Boeing has not been found, the families of victims have already begun to receive compensation. For every life lost, the fee is $ 5,000. As experts in insurance stress, relatives of three Americans who were aboard the aircraft can claim a lot more money. In fact, millions of dollars, since in U.S. the "compensation for loss of life" has many parameters and is "priced" differently than any other country in the world.
