It is even less likely if one looks at the sworn evidence of the witnesses on the Mull at the time of the crash; The 2 Lighthouse Keepers (who were trained Met Observers) estimated the visibility at their respective locations on the Mull as "15 to 20 metres at most" and "10 metres or less". Other witnesses gave estimates of "10 to 15 feet" and "9 or 10 feet maximum" at their respective locations.
