hope AC's 777 isn't any worse for the wear by breaking the sound barrier!

So flight is earlier than the scheduled flight time by 3h? On a route that normally just takes 7-8h? That doesn't sound right.
Anyway, googled the flight and it's still in the sky at the moment. You are probably looking at today's departure time and yesterday's arrival time.
