> In May 2021, aerospace engineer Richard Godfrey suggested an examination of historical WSPR data to further define the flight path of Malaysian Airlines flight MH370 on 8 March 2014, suggesting that there were "518 unique transmission paths that cross the area of interest around Malaysia, the Malacca Strait and the Indian Ocean. With the WSPR data provided every two minutes and the ability to check against the satellite data every hour it is possible to detect and track MH370 from two independent sources."[7]
However, the method used in this article is highly questionable; The reflected signal energy from aircraft in such distances is very small (inverse square law), much smaller than variance on the regular skywave signal due to multipath propagation, which can vary by tens of dB within seconds. Such difficulties make it necessary to use more advanced methods for radar applications at such distances in this frequency range (Over-the-horizon radar).
At the rist of being the armchair skeptic, my guess is he was looking at some points on the map and looking for signals, and interpreting noise as "Look, that's the wire being tripped right there!"...
