bbm - I tend to want to defend the pilots, too, but one bit of information that came out was that the pilot (we can only assume the M gov't checked his voice - and found it was indeed him) said "good night" to the controllers AFTER he turned off the transponder.
That is pretty damning evidence to me.... and THEN you look at the other things - that someone in control of the airplane knows what they are doing - know how to fly between radar paths, knows how to turn off other tracing devices. THEN you look at his recent history - upset with government, attended trial, etc. I know, I know - lots of pilots have strong opinions - but how many would care enough to attend the trial of someone on the day they are scheduled to fly all night? That shows a level of conviction that is unusual imho.
