Inmarsat offers free airline tracking

[mhm]

UK satellite operator Inmarsat is to offer a free, basic tracking service to all the world's passenger airliners.

The offer follows the case of Malaysia Airlines flight MH370, which disappeared without trace on 8 March.

It was very brief electronic "pings" from Inmarsat equipment on the lost plane that prompted investigators to look for wreckage in the Indian Ocean
