>The fastest transatlantic crossing belongs to BA Concorde, which flew from New York to London in two hours 52 minutes and 59 seconds in 1996 - hitting a top speed of 1,350 mph.
That was the fastest commercial flight. The fastest transatlantic crossing by an aircraft was the SR-71 in 1974:
1 hour 55 minutes
Average speed over 1800 mph

- themodelplumber 7y ago> 1 hour 55 minutes Average speed over 1800 mph It felt weird that my first reaction was to wonder what took so long. For some reason I was thinking that surely the Blackbird could make the crossing about 60 minutes faster than listed. Looking at a map, I saw that the air line distance from Fortaleza to Dakar is just over 1,900 miles though. So I'm thinking "transatlantic" must mean more than my own basic definition. (Plus I don't know if these locations would have enough runway for the SR-71, or if the reason we haven't heard of faster is because US taxpayers aren't footing the gas bill to arrange a shorter route)
- smoyer 7y agoThe blackbirds have to show down to refuel.
- themodelplumber 7y agoI don't understand. Are you saying they refueled over the Atlantic while setting this record?
- chipsa 7y agoMost long distance Blackbird flights involved taking off at low fuel weights, then refueling shortly after take off. So yes, the record probably involved refueling over the Atlantic.
- anonsivalley652 7y agoThey refilled immediately after takeoff. Then, if they got a full tank of JP-7 around NYC, that gives them a one-way range of 3250 miles, which is less than the 2999 nautical miles of LGA -> LHR. The SR-71's range is a hair over 3200 nautical miles. Getting a full tank of the special JP-7 or landing around LHR would be do or die time, because that would be just about bingo fuel.
- pwg 7y agoThe link posted by @RcouF1uZ4gsC contains a graphic that shows a 'refuel' point over the mid-Atlantic and the linked article says this: > ...it needed a minimum of one in-flight refueling, thanks to the astonishing amount of fuel it consumed while in afterburner. ... Having already surged across the Atlantic in a sustained supersonic cruise at speeds in excess of Mach 2.5-2.6 ... Sullivan began a descent that would bring him to the only refueling point of their mission. After tanking up, the duo climbed away and once again nudged the throttles ahead. The time taken up by the in-flight refueling was deemed virtually negligible when the Blackbird flew through the London gates. So, according to the linked article from @RcouF1uZ4gsC, yes, the record time included one refuel during the NY to London route.
- anonsivalley652 7y agoSlow* Not necessarily. The SR-71's range was 3250 miles, which is ~10% less than the NYC to LHR distance. It might encroach bingo fuel, but maybe not. If they refilled to completely full in New York, they could either refill or land once reaching the London area.
- oliwarner 7y ago> Slow* I do enjoy the idea of a mid-air transatlantic showdown for fuel though.
- diego 7y agoIf you read the article, you will see that this is about flying between New York and London.
- themodelplumber 7y agoI did read the article: "The fastest transatlantic crossing belongs to BA Concorde, which flew from New York to London in two hours 52 minutes and 59 seconds in 1996 - hitting a top speed of 1,350 mph."
- anonsivalley652 7y agoPSA: If you don't want people to quote HN guidelines, please don't assume they haven't read the article. Thanks.
- aeleos 7y agoIt looks like this is not the fastest commercial flight but the fastest subsonic flight. The Blackbird and Concord records you are talking about are a different category.
- RcouF1uZ4gsC 7y agoThe Concorde was definitely supersonic. That was the whole point of the aircraft to enable commercial supersonic travel.
- zamadatix 7y agoI think there was some confusion on what the "this" keyword is referencing in the comment (one of the reasons I hate it in code :))
- mcv 7y agoIt's weird to see people continuing to argue about this, when the article itself makes pretty clear that this is about the subsonic record. Concorde and Blackbird are completely irrelevant. Of course they're faster, but that's not the point. The entire reason a subsonic flight could go at speeds normally only possible to supersonic aircraft, is because of the speed of the jet stream driven by Ciara. The plane is flying at subsonic speeds within a moving pocket of air that adds quite a lot to that speed. That's the interesting part about this story.
- Piskvorrr 7y agoIndeed, the airspeed/groundspeed distinction continues to confuse people. The plane still moves at subsonic speed, as that's w/r/t surrounding air.
- anonsivalley652 7y agoTL;DR: Rocket plane: hold my beer A rocket-powered plane vaguely similar to the X-15 could cut that to about ½ to 1/3 the time. That would likely require a space suit, an RCS, ablative coatings and exotic materials. Ejection seat?: good luck with that over mach 3.
- baq 7y agoa ballistic flight could do that distance in 30 minutes. musk wants to commercialize spacex's new big rocket - aptly named "starship" - in that way. we'll see if he can get over environmental concerns, the noise during takeoff will be life threatening.
- TeMPOraL 7y agoThe Kerbal player in me has a tentative solution: add a first stage for takeoff assists made of jet engines, not rocket engines. It would still be noisy, but perhaps not that noisy; after boosting it to some sensible altitude, the stage would detach and Starship's rockets would take over. The jet engine stage would of course be recoverable (parachutes, or it could fly itself back like a drone, because why not).
