Groundspeed Records

[CBreuer]

And another speed record enroute from Wake Island to Los Angeles. I am experiencing a very strong tailwind of 122 knots while the B747 was climbing from FL310 to FL330 somewhere over the Pacific. I flew at a constant speed of Mach 0.865. I think 635 knots ground speed is pretty fast
   

If you have tried to cross the Atlantic last week and fly with the jet stream you could have caught a 220 knots tailwind traveling to the East. It would not be very smart to fly the opposite direction - unless you have enough fuel and a lot of time.
