I can't agree more , reading this every bullsh*t alarm in my brain was triggering. In his report Mr Godfrey never mentions the frequencies used for the WSPR transmissions. This mode can be used on VHF/UHF frequencies where it may reflect from aircraft. But 95% of WSPR transmissions are on frequencies below 30 MHz and most likely below 20 MHz. These have long wavelengths and highly unlikely to be affected by an small (in wavelength terms) aircraft. If it could be affected by aircraft then Mr Godfrey would have to take into account the movement of every aircraft in that region at the time which he doesn't appear to be doing. As a note of explanation I'm a radio amateur and a WSPR station operator , its a brilliant tool for propagation studies but not for this.
