February 27, 20242 yr Ummm...No. "Supersonic" means travelling at an airspeed faster than the speed of sound at that air density and temperature. A high groundspeed due to a 250 knot jetstream tailwind does not mean the jet is travelling through the air mass at faster than Mach 1.

February 27, 20242 yr So, based on the chart at 2:27, FlightAware shows ground speed, not air speed? Dugald Walker

Flightaware cannot see the airspeed indicator in an aircraft. I believe that the title of the video is what is known as clickbait. "The aircraft achieved a ground speed of more than the speed of sound" is much less catchy but much more true. Edited February 27, 20242 yr by Reader

February 28, 20242 yr What happens if an aircraft travelling at a ground speed of over 800 mph (due to being pushed by a very fast jetstream) suddenly drops out of that regime into normal atmospheric conditions? Is that possible, or are the edges of the jetstream very well defined and stable (so that this can be avoided)?

February 28, 20242 yr Author Most YT videos have clickbat titles these days. And in this case, as aviation enthusiasts, its obviously clear to us that the aircraft in question weren't supersonic in their domain. The video did clarify this within a few minutes. And the title of the video did include question marks. My title didn't. 🥴 Still a record, though, but not in terms of total flight time. This may be a myth, but wasn't it US bombers in WW2 that first encountered the jetstream, when they noticed their groundspeed was zero? Edited February 28, 20242 yr by martin-w

February 28, 20242 yr Had they gone past M 1.0 though, maybe a creaky old airframe way out in the back of some desert boneyard might have yawned and said "Been there, done that.' https://en.m.wikipedia.org/wiki/Douglas_DC-8 On August 21, 1961, a DC-8 broke the sound barrier at Mach 1.012 (660 mph/1,062 km/h) while in a controlled dive through 41,000 feet (12,497 m) and maintained that speed for 16 seconds. The flight was to collect data on a new leading edge design for the wing, and, while doing so, the DC-8 became the first civilian jet – and the first jet airliner – to make a supersonic flight.[29] The aircraft was DC-8-43 registered as CF-CPG, later delivered to Canadian Pacific Air Lines. The aircraft, crewed by Captain William Magruder, First Officer Paul Patten, Flight Engineer Joseph Tomich and Flight Test Engineer Richard Edwards, took off from Edwards Air Force Base in California and was accompanied to altitude by a F-104 Starfighter supersonic chase aircraft flown by Chuck Yeager.[30]
