British Airways 777 plane blown across Atlantic at near supersonic speeds jetsteam

Ive saw 702mph ground speed on a flight(KC-10A)from Yokota to travis. FE turned the #2 inu to wind position, 189kt tailwind. Don't recall what true airspeed was, probably bumping 400 kts but the overspeed warning was activated. Landed 1.5 hrs early

Same thing happened to me once driving thru Kansas in a windstorm.

Very cool.


And...GAH!...journalist sticking his opinion in there:
"Jetstreams are caused by the rotation of the earth and heat from the sun and global warming is thought to play a factor."

I forgot, there were no jet streams before global warming.

But that is accounted for in the fuel load, we have been putting on 15,000-20,000 less kilos per flight on the way back.

UN-forcast = greater than published or the 90 day historic route predicted fuel load. 15k kilos is nothing to a 4 motor bird. At AA we have our own approved meteorological department working with dispatch to calculate our fuel. They get it wrong sometimes. I am talking about winds in excess from forecast.
The Captain can over-ride that and request more/less. The flight release is a joint sign-off between the Captain and the dispatcher.

That was Lyn, I Broke the sound barrier with a strong tail wind. It was in a Mustang, of course.
