Can You Beat 622 Knots?

I think 695kts is going to stay the highest observed ground speed for a while, it was an exceptionally fast tailwind those aircraft flew in.
I've not seen anything close to those speeds since then, or ever before.

Yes, I agree. In which part of the world did you see 695 knots? With close to a 200 knot jetstream I suspect that it was in the Far East somewhere?

North Pacific Ocean area.

Thanks - I will keep my eyes open there....

A colleague of mine is a captain on the B747-400. He took this picture on the 17th of January 2013 when operating the BA 274 from Las Vegas to LHR BA 274.jpg

Not sure if this is accurate, but this is today. Converted that is 718 knots!KU102 220215.png

And another one, a Delta E Jet either crashing or landing in Seattle at 736 knots. That CAN NOT be accurate.DL5784 736knot.png
