I learn something new everyday. I am not a pilot nor have I ever flown an aircraft. I'll take your word for it but you might be interested in some guy named Les Abend who has been a 777 pilot for 29 years and wrote this:
"First, the focus on the airplane's transponders, the device that transmits a discreet signal to Air Traffic Control (ATC) radars, might be misguided. The 777 has two transponders. A failure of one would send a caution message visible to the crew. They would then select the alternate transponder with barely a second thought.
A double failure? Not likely, unless there was a serious electronic systems failure (more on that later).
The only other plausible explanation would have been that the crew moved the knob to the off position.
No professional flight crew would knowingly turn off a transponder in flight."
here is the link for the whole article:

I admit I don't know what I am talking about. I only go by what I've read from the so-called experts on the news and internet. They all have been saying pretty much the same stuff when it comes to the transponder. Other experts say that you may have to re-toggle (reset) the transponder if it is giving out strange data but there really is no good reason to shut it off unless you want to hide. Not calling you out, just wondering what you think of this pilot with 29 years flying 777s saying:
No professional flight crew would knowingly turn off a transponder in flight."
If I'm reading this article right, you are saying one thing and this pilot is saying something else. Sort of like all the info the public is getting about this incident.
