Retired British aerospace IT specialist Richard Godfrey, another person who has been pulled into the MH370 vortex, believes he has now pinpointed a much smaller search area, using innovative analysis of short-wave radio test transmissions made routinely by ham radio enthusiasts. This should allow a more concentrated search by the drones, making several passes over the same area.
"They record 1.7 billion records a year in their database. Imagine a huge fisherman's net, across the globe, full of radio signals. Every time an aircraft passes through this net, it breaks a hole in the net. That tells me where an aircraft was at a particular time. Over the six hours of MH370's flight into the southern Indian Ocean I have been able to find 313 anomalies in the radio signals at 95 different points in time. That gives you a much more refined flight route, and a more accurate determination of a crash location."
Richard's method is currently being tested by the University of Liverpool, which expects to establish how valid it is later this year.
