In answer to the pings, goldie explained that way back on thread 2 I think 
The equipment that sends the ping is not the same as the other two transponders and is located somewhere different I think. That is one reason why it could point towards foul play as the pilot or hijacker or whoever would know to disable the transponders but they wouldn't know about the ping.
I can't remember the technical details but I think that's the gist of it.
trixy I think Honey is getting at the fact that too much blame is being assigned to pilots when for all we know they could be heroes and or victims of a tragic accident. It is very hard to see what we can only assume to be innocent people being dragged through the press and maligned or the target of suicide claims, damaging for the families of those involved.
We may never know what happened. But one of the good things the Malaysian government said was innocent until proven guilty.
