New York flight goes SUPERSONIC

I'm not sure why this is news, this has been happening quite a bit recently, with the jetstream being where it is. I've seen quite a few planes grounding over 1200 km/h crossing the Atlantic. (Eastbound of course)

Tried to edit and it cut it short. Think it was a record run for a Non Super Sonic jet with a ground speed over 700. Normal is 550 or so and a 7 hour trip.

Wonder why it made news looks about the same but they said it was a record ??

Speed of sound is in relation to the air around the aircraft. If you are flying with a 200mph tailwind, then the speed of sound would be whatever it normally is plus 200mph. I really doubt that this Boeing 777 was almost supersonic.

Close, but the speed of sound is whatever it is period, no plus or minus for wind! Speed of sound depends solely on the density of the medium through which it travels. Speed of sound at sea level, about 760 MPH. At FL450, about 650 MPH. The 777 was probably cruising at around .84 Mach or 84% the speed of sound, then you get the groundspeed by adding the tailwind. TAS was around 460 Knts. I'm guessing that's what you meant to say but didn't exactly.

Now here I tried to be the no comment one by basically saying nothing and here you are the one that jumps in with a correction. LOL. I will add though, while I am in here, that you are very correct. There is a lot of confusion at times of ground speed and KTS(TAS) but as usual, your clarity is impeccable

Thanks, didn't man to steal your thunder, just thought this would be a noncontroversial clarification for what trips a lot of folks up. That would be TAS, IAS, GS, and Mach. The numbers and differences get much bigger in the flight levels as you well know. Cheers!

Have a good 'un. I'm outa here. LOL

You gotta admit that it sounded good and was a wonderful PR ploy for SpeedBird.

Thanks for the negatives, I was just reporting what King 5 News reported. Hope you find some meaning in your life.

BA 777-200 hits 745knots on JFK to LHR flight

Also reported here:
Concorde may have been retired but a British Airways passenger jet approached supersonic speed this week as it rode a surging jet stream from New York to London.
The Boeing 777-200 jet reached a ground speed of 745mph as it rode winds of more than 200mph across the Atlantic. At ground level, the speed of sound is 761mph.
The happy result was a flight time of just five hours and 16 minutes for BA114, which arrived an hour and half before schedule, according to the tracking website, FlightAware.
Dozens of other flights also benefited from the jet stream’s winter surge, but those same windshave also triggered severe storms across Britain.

Made King 5 News here in Seattle. They caught a heck of a Jet Stream run and set a record or near record (missed that part) in atlantic
