Error : "Close up of engine nozzles of production Concorde G-AXDN. The nozzle consists of tilting cups"

Look at the photo, described as "Close up of engine nozzles of production Concorde G-AXDN. The nozzle consists of tilting cups." : that's not G-AXDN. AXDN is the first pre-production Concorde (01), and the tilting cups were put first on F-WTSA (02).

Speed of sound

The second sentence of page Concorde is this: "It had a maximum speed over twice the speed of sound at Mach 2.04 (1,354 mph or 2,180 km/h at cruise altitude), with seating for 92 to 128 passengers." The km number is 2500, not this 2180. It was important aim of the factory to catch the dream limit of 2500 km/h! >> https://s11.metric-conversions.org/speed/mach-to-kilometers-per-hour.htm

The speed of sound varies with altitude - the quoted website only gives the conversion at Sea Level - the cruise altitude for Concorde is ~ 56,000 feet (17,000 m).Nigel Ish (talk) 13:42, 19 January 2020 (UTC)

Oh, sorry, now I learnt something. (or we learnt :D) Have you oppinion about max km speed of Tu-144? (what isn't in its page) Showowindow (talk) 14:00, 19 January 2020 (UTC)

Concorde fleet

The text in section "Aircraft on display" is mistaken. Only 20 units were built, not 26 units. Several sources confirm this. Two aircraft were prototypes (sn 001 and 002), two were pre-production (sn 101 and 102) and two were development aircraft (sn 201 and 202). The source "Towey 2007" (per infobox on Concorde aircraft histories), cite "20 (including 6 non-airline aircraft"). 18 remain preserved (sn 203 was destroyed in accident and sn 211 was scrapped).--PauloMSimoes (talk) 01:52, 17 March 2020 (UTC)

Thanks. I put the count back to 20 (the change was made 2 days ago, perhaps a misreading of the infobox). --Wire723 (talk) 11:16, 17 March 2020 (UTC)

Yes, both the other user and I both misread the Infobox info, thanks. Concorde aircraft histories explains the non-commercial and commercial breakdown. -Fnlayson (talk) 18:31, 17 March 2020 (UTC)

Reminder about legal subsonic requirement

I have just heard (Master Minds quiz show, Game Show Network on cable TV) that law was passed to forbid Concorde from flying supersonic over U.S. This is because of sonic boom. Carlm0404 (talk) 00:58, 21 July 2020 (UTC)

It isn’t plausible that the Congress would pass a law of this kind directed at an airplane type. It is much more likely that the law prohibited any civilian airplane from supersonic flight over the territory of any US state. Alternatively the law might prohibit supersonic flight over mainland US without the permission of the Defense Department. Dolphin (t) 01:07, 21 July 2020 (UTC)

You are thinking of FAR 91.817. You will notice it does not mention Concorde. - Ahunt (talk) 01:14, 21 July 2020 (UTC)

Exactly. One of the reasons that the US supersonic airliner program failed was because of environmental concerns that were just coming to the forefront at that time, ie. late 60s/early 70s. The Boeing 2707 would have likely faced the same restrictions as The Concorde had it been produced. Those restrictions are still in place today though the FAA is looking at modifying the restrictions to allow for the newer supersonic transports now under development that have hope to have reduced sonic booms. - BilCat (talk) 01:40, 21 July 2020 (UTC)

French flagman aircraft

At the moment, the article contains this: Presidents Georges Pompidou, Valéry Giscard d'Estaing and François Mitterrand regularly used Concorde as French flagman aircraft in foreign visits. Does that make sense, and work well in idiomatic English – even in an aircraft article? Whilst I understand what it means I find it a somewhat odd wording … but maybe it’s OK like that so I’m not starting a huge war over it! Just interested in the (to me) apparent oddness.

Nope, makes no sense to me like that! Where I live (Canada) a "flagman" is a person who signals traffic at a construction site. I think it means "flag aircraft", but it would be better to explain it something like: "used Concorde as French government charter VIP aircraft for foreign visits."- Ahunt (talk) 16:56, 11 December 2020 (UTC)

11 September 2001

"The first flight with passengers after the events of 11 September 2001, landed shortly before the World Trade Center attacks in the United States."

This section has had edits and reverts (see article history) but still has issues with intelligibility and accuracy. The author is trying to say that there was a test flight (to/from Heathrow in the UK) on 11 September 2011. It landed around the time of the attacks on the World Trade Center on the same day (takeoff at 10:30 BST; landing at 13:50 BST — after the first plane hit the North Tower but before the second plane hit the South Tower) . It was not a commercial flight as only British Airways engineering staff were on the flight. It was the first flight with "passengers" (aka non- flight crew) onboard since the crash on 25 July 2020.
