Seriously?!?!? Falling asleep is clearly at epidemic levels. This coming from the director of an agency of incompetents. How many times has a terminal needed to be cleared and everyone re-screened because the TSA officer has fallen asleep and someone walked through the exit???

A possible grand idea hatched from a hoot that was forced to resign suddenly becuase he was so inept and despised by just about everyone but possibly Vlad Putin.

Questions I have not seen addressed (at least publicly):
1) Was Capt's flight sim data simply deleted
or wiped to defeat forensic recovery?
2) Any background on either crew members religious (and/or fundamentalist) leanings? Malaysia is predominately Muslim. Just saying....
3) Was crew randomly assigned or did they buddy bid or otherwise ask to fly together?

Once data has been overwritten 4 or more times, it is absolutely impossible to figure out what was there before. And most off-the-shelf data wiping tools will do multiple overwrites.
If there is any source/evidence that a government agency can recover data that has been specifically wiped, I'm willing to listen. But short of that evidence, the idea goes against everything i know about hardware, software, and physics.

Listening to the media pretend to understand how a 777 works hurts my ears.
All this talk about programming, or pre-programing a turn is based on what?
I can use the FIX page to install a LAT/LONG or a Published Intersection and then use heading select to steer to that point. I can also just use MCP heading select to simply steer, no FMC input required.
Did this flight use CPDLC/ADS, FANS 1/A? Did the flight's FMC downlink a changed route via ACAARS (and if so why don't they look at the last waypoint in that downlink)? If CPDLC was used, there is the ability to uplink a new route, and if the crew accepted and executed an upload the aircraft would fly that route (on AP).
Just curious how sure they are of a pilot installed/uplinked a FMC flight plan vs. a heading select course on AP.
PS. To the media cursing this thread for info, please stop embarrassing yourselves.

After many wipes you lose the ability to identify discrete data quanta and then get into probabilities. Advanced software can attempt to rationalize those probabilities (akin to a dictionary attack). Wouldn't work for pure random numbers, saying a crypto key but apparently is useful where the source data has some degree of predictability.
Also heard that each write cycle may write in a very, very slightly different location which helps isolate "layers" of over-written data (the are mechanical devices after all).
