that may be the case but you certainly have more ammunition with evidence in hand. Also you could post it here for our infoDunno...the service writer, who is always debatable if they know their ass from a rock, says they can DL all that data...engine temp, speed, gear, throttle position, ambient etc. during the episode.
I've been thinking though, I don't recall EVER hearing the fan go to high speed. Ya'd think it would sound like a helicopter if it was overheating.
