Fullwings,
From the very beginning, the term ‘Ghost Flight’ was used to describe ‘silence’ and lack of data to the portion of flight beyond the primary radar detection to the end of flight, which could possibly be a straight line.Not any portion prior.
There is no evidence of:
-Autopilot disconnect
-Autopilot reconnect
-Transponder being ‘switched off’
-Hypoxia
-Following any airways
-Unlawful interference
-Tripping transponder CB
-“Satcom stopped working for about an hour”
-“Mechanical accident failure”
-Nefarious pilot
Dave,
Speculation is only natural for human who can’t refrain from making a statement before having their own thoughts sorted.
