Merge

So, can anyone think of a good reason why this airplane should exist as two separate articles? McNeight 18:35, 21 February 2006 (UTC)

All I've got is that you'd wind up with one really lengthy article. The 717 is a pretty significantly different aircraft from the DC-9-30 (I've often wondered why the MD-80 isn't separate, actually), what with the new engines, avionics, and major airframe revisions. It's not quite the Boeing 747-8, but a similar comparison can be made. ericg ✈ 03:13, 23 February 2006 (UTC)

I agree with ericg's points above but also think that it is a pretty significant name change - if you flew on a Boeing 717 maybe you want to find out about it and not its predecessors. The DC9 article goes back decades but this final variant of it was significantly different and should be recognised as such with its own page. It also keeps the sequence of Boeing 7x7 articles and fits well in the encyclopedic nature of Wikipedia and thus, as it's doing no harm and isn't clearly superfluous, I'd keep it. Iancaddy 21:11, 23 February 2006 (UTC)

Yeah, we definitely should keep these seperate. There is a huge difference between the dinosaur DC-9s that Northwest owns and the 717s that AirTran owns. Tboger 01:50, 24 February 2006 (UTC)

It's hard enough to sort between MD-8X series and DC-9s so to combine the modern 717 it the antiquated grandparents would be impractical. The same thinking applies to the A350 being apart from the A330, on which it is based. MitchRose

Due to the old 717 and the new 717 creating confusion, I agree - keep them separate. If we combine them, the header should be the MD-90 and the 717 would be an "later in the MD-90's life" addition. GURoadrunner

I believe that keeping them separate would be the best idea. Most of the world continues to see them as a different plane and I don't see why we should merge them. Their histories are different anyway. --themit 03:39, 10 March 2006 (UTC)

I was recently considering suggesting moving MD-80 out of the DC-9 article. I think 717 should stay 717, with a small mention in the DC-9 article, linking to it. In support of the merge, though, look at the 737 article...it's all one article, from the 60s to present. The Next-Gen 737 is just as different from the classic 737 as the 717 is from the DC-9. The situation is similar, so I see how a merge would seem logical. However, the difference is the name-change, Boeing buyout, etc. We don't have one model name with the DC-9 series. While the DC-9, MD-80, and 717 are just as similar as a 737-200 is to a -300 is to a -700, the Douglas aircraft definitely need to be separated, with linking in between them. It will help the average user differentiate them and, with any interest, find out the lineage of the aircraft.

I support keeping them separate. --Bryanmenard 21:50, 13 March 2006 (UTC)

717 Cockpit Layout

I made a quickie edit to the end of the 717 section correcting the statement that the 717 shares the same cockpit as the MD-90 (the -90 has the same cockpit as the -88, 717 has the MD-11 EFIS system). Someone might want to restate what I said, I'm not sure if it reads as well as it could. Uniuniunium 19:43, 18 March 2006 (UTC)

Split

IMO the MD-80 and MD-90 sections should be split from the DC-9 article. They are a different generation of aircraft, just like the MD-95/717. Who is able to to the split? Andros 1337 16:44, 13 July 2006 (UTC)

• True. Spliting into DC-9 and MD-80/90 seems reasonable. -Fnlayson 20:15, 13 July 2006 (UTC)
  • I copied the MD-80 and MD-90 content from here to the MD-80 article and removed a lot of the DC-9 content. It needs the background redone and some clean-up, but it's a start. -Fnlayson 05:51, 14 July 2006 (UTC)
• If only DC-9 remains (no MD-xx ones), shouldn't this entry also eventually be renamed to Douglas DC-9? Oyvind 18:45, 14 July 2006 (UTC)
  • This article is already named that. Maybe you mean remove the MD-XX content from this one. Which should be done - Fnlayson 20:58, 14 July 2006 (UTC)
    • No, I actually did mean Douglas DC-9, as opposed to McDonnell Douglas DC-9 that the article's called today... I think DC-9's were introduced and largely manufactured by Douglas alone, before the company ended up being McDonnell Douglass and eventually Boeing, isn't that correct? It might still make sense to have at least a reference to MD-80/-90 series, or some minor information still... galar71 21:15, 14 July 2006 (UTC)
      • The last DC-9 was delivered in 1982, which is 15 years after the Douglas-McDonnell merger (1967). So most DC-9 were made by MDC. But I can see good reasons for Douglas or MDC. - Fnlayson 21:55, 14 July 2006 (UTC)

I'd say the DC-9 was developed and produced (at least for about 2 years) by Douglas aircraft so it should be moved back to Douglas DC-9. There's no reason to keep it under MDD with the split of clearly MDD based evolutions MD-8x and MD-9x. --Denniss 20:46, 20 July 2006 (UTC)

• And design and development is a good for to name it Douglas DC-9. - Fnlayson 03:48, 21 July 2006 (UTC)

propfan MD-80

I read that during a period of unusually high fuel costs, MD built one -80 with propfan engines (these look like turbofans, but with a propellor attached to the rear; they are known for their effeicency). After some initial hype, no orders came, and the model (I believe it was a one-off, more of a demonstrator than anything else), was scrapped. There has been intermitent talk of using propfans on civil aircraft since then, but it has not come to anyhting. 152.163.100.65 00:41, 24 June 2006 (UTC)

There should be more coverage on the MD-91X and MD-92X propfans. 76.66.195.63 (talk) 08:40, 1 December 2008 (UTC)

Rename article Douglas DC-9

• Anybody has a problem with renaming this article Douglas DC-9 (from McDonnell Douglas DC-9)? The DC-9 was designed and started production under Douglas Aircraft. -Fnlayson 02:43, 24 July 2006 (UTC)

• I'm all for it, but I'm not so sure about Wikipedia's policys in regards to a situation like this. I've been told before that if a company merges, changes its name, or is taken over, it assumes the new company's name in an article. I'm not entirely sure in this case though. --KPWM_Spotter 03:04, 24 July 2006 (UTC)
  • Maybe there is a policy or something on that, but I couldn't find it yesterday. - Fnlayson 15:32, 24 July 2006 (UTC)
• Policy (Wikipedia:Naming conventions (aircraft)) is vague on this. We should probably stick with the final manufacturer, not the first in the name. -Fnlayson 16:48, 27 November 2006 (UTC)

Uhm, actually, I'm all 'for renaming, as official documents (such as this official airport planning document issued by MDD and dated June 1984, long after the merger between Douglas & MD) indicate that the DC-9 was never actually sold as "McDonnell Douglas DC-9", but as "Douglas DC-9". This kind of makes sense as Douglas developed the Series 10 to 50 on their own, without McDonnell having any part in it. So the "Douglas DC-9" designation reflected that and was probably also retained because at the time Douglas was much more of a household name in civil aviation. The MD-80 - the first version to be fully developed after the merger - was consequently the first to reflect the change in manufacturer name and type designation. Now, the "McDonnell Douglas DC-10" is a different story, as its development only began in the year of the merger. As to why the DC-designation was retained, I can only guess - again probably because the "DC-" had a bit of a history (DC-3, DC-4/-6/-7, DC-8, DC-9) in it.--afromme 00:34, 31 January 2007 (UTC)

• OK, it doesn't really matter to me. Anybody see a problem with moving this to Douglas DC-9 ?? -Fnlayson 00:43, 31 January 2007 (UTC)

Production dates

is it just me or does this article seem to suggest two dif dates for when production was ceased?

It does, but that's true... the "DC-9" went out of production in 1982. The "MD-80", which is a new name for the DC-9 family of aircraft, kept going for a while, eventually on to the Boeing 717 model after they bought MacDac. It's "this model stopped production" versus "the last model produced in the family of DC-9 aircraft stopped production". Georgewilliamherbert 00:55, 22 March 2007 (UTC)

• DC-9 family is stated, clearly I think. The MD-80, MD-90 and 717 all descended from the DC-9 and are thus part of the family. -Fnlayson 01:32, 22 March 2007 (UTC)
  • I've tried to clarify things. I removed the airlines from the 717 sentence in the lead. Hope this helps.. -Fnlayson 15:29, 22 March 2007 (UTC)

new lead photo

The picture in the info box should be replaced with a more modern one, and one that is of a plane in use..not a cutout. Northwest still has plenty of DC-9's out there..and in the new livery. I'm sure a photo of one of those will suffice. —The preceding unsigned comment was added by 66.53.229.74 (talk) 04:28, 27 March 2007 (UTC).
