Tail wind tall tale?

I read yesterday an item written by a reputable person who is also a private pilot, seemingly indicating that he experienced a 168 mph tail wind on January 1, providing a ground speed of 657 mph, I believe heading east across the US toward Washington, D.C. Is that possible? I can't provide a link, but it's in a tweet dated January 1 of @JamesFallows.

200kts+ jetstreams are not uncommon .That's 230mph+.

I had a 220kt tailwind once over Newfoundland, giving me a groundspeed of over 700kts.

I can't provide any private flight tall tailwind tales, but in the 90's flew in a UTA DC-10-30 from MIA-CDG in 5hrs 20mins approx due to extremely strong tailwinds. Like being on a Transatlantic travelator ;-)

I remember my mother, who was deathly afraid of flying until she discovered the miracle combination of valium and bourbon, bragging about setting a speed record between KLAX and KLGA aboard a Convair 990 Coronado in 1963. Total elapsed time was slightly more than four and one-half hours; they had ridden a strong jet stream the entire journey.

Landing a CV990 at LGA must have been fun

There is currently (Thurs 3rd) an area of 160kt jet stream winds positioned over the north-east USA. This would have been positoned over the center of the country previously.

Weather model charts show it as being about 500nm long (E-W) and 200 wide N-S), with much lower speeds outside that region (and at lower altitudes). A flight plan would be able to take advantage of the winds, but the whole route could not be at top speed.

My "record" is 715 kts over the Pacific, with a similar tailwind.

For some reason my photographic evidence doesn’t upload but recently over NE Russia we experienced OAT of -71C at FL320 which is a personal record for me.
Couple of months ago, same area of operations we hit 185kt headwinds and miserable turbulence.

Many years ago I had the displeasure of encountering the Mediterranean jet en route Akrotiri to Luqa. It was much worse than forecast; after the first couple of beers (post landing!) we did some sums and worked out the average headwind was 200kt.

I did a quick flip through some flight tracks on 1Jan, and the fastest I could find was a B787 LAX-LHR. Peak ground speed was 735mph, with a filed speed of 564mph, giving a tail wind of about 171mph.

The total flight time was about 45mins shorter than average, because only a limited duration was spent inside the jet-stream. The track was longer in distance than the great-circle route, but still faster overall.

Obviously flights in the opposite direction use a more polar route to avoid the head winds.

Tail Winds

I came back on MH1 23rd December 2018, 2 hours into the flight the screen was showing 172kph tail wind and OAT -71°C
Nothing spectacular but could have been chilly if someone opened a window.

There are I think size limit on images. As I recall, pixels and file size both restricted. The error messages are not particularly explanatory (British understatement.

Perhaps not perfect but I have a speedometer on my phone which operates via GPS. On a flight from Manchester to Tel Aviv in January 2017 on an easyJet A320, I recorded a maximum speed of 646mph. And we only landed about 30 minutes ahead of time. So 657mph seems perfectly reasonable.
