I don't buy it first of all, but secondly, the 777 Flight Management System (FMS) has the ability to load two routes, a Route 1 wich is our normal route, and a Route 2, which we load with our divert points and divert airports.
If they were having a mx issue, and they'd decided to divert, all they would have to do is push two buttons on the FMS to move from Route 1 to Route 2: "Activate" and "Execute" and the airplane would now fly the route 2, to their divert airport.
I'm in ATL at the moment, on my way to Dubai tonight. I'll keep my eyes open for the Malaysian 777, who might be trying to shadow us....
