Wikipedia:Featured picture candidates/C-141 Starlifter exhaust.jpg
I stumbled across this one day, and thought: wow, that needs to be featured! Ingoolemo talk 08:09, 2005 September 7 (UTC)
- Quite nice, but is there a bigger version available? Raven4x4x 10:12, September 7, 2005 (UTC)
- It's a very nice picture, but I'm not sure it illustrates an article very well. It's used on C-141 Starlifter, but it really doesn't show us very much about that aircraft. It's also used on Pratt & Whitney and Pratt & Whitney JT3D, but we can barely see P&W's engine in the photo. I guess an FP for the P&W articles would be a nice big clear image (either a photo or a diagram) showing the engine, with the casing removed so we could see all the stuff inside. It would be a better fit for contrail, but even then the images there are really better for that purpose that this. -- Finlay McWalter | Talk 19:48, September 7, 2005 (UTC)
- Support -- What about placing the picture in the article Exhaust gas? TomStar81 00:32, 8 September 2005 (UTC)
- Good idea, I've just done it. - Mgm|(talk) 12:27, September 8, 2005 (UTC)
- Bad idea, it's a clearly vapour trail rather than exhaust gas. Dunc|☺ 20:26, 8 September 2005 (UTC)

- Unfortunatly, I am not real familar with jet engine, so this is just speculation on my part, but I would imagine that its probably both. A jet engine relies on a mix of avaition fuel and air to combust, so the vapor trail most likely contains exhaust gas. In either case, because we are all agreed that the trail originates in the engine it is going to contain exhaust gases.TomStar81 03:07, 9 September 2005 (UTC)
- But, AFAIK CO2 is a colourless gas, blackness in smoke for example from steam locomotives or diesel cars is caused by unburnt or partially burnt hydrocarbons. You only get black smoke from a steam locomotive (driven properly) when it's running on bad quality fuel. Aeroplanes on the other hand have to fly on very high quality aviation fuel.

- I agree. You can see that the trail starts some distance behind the engines, therefore it's vapour, and not the visible exhaust, although there would be exhaust gases mixed in. Possible addition for vapour trail?
- Though a great pic, I don't think it demonstrates much of anything about all the ideas put forward (aircraft, engines and/or exhaust/vapour trail) all of which could probably be demonstrated in better images. Also the setting sun is not only distracting, but hurts my eyes and from what I see (just by resizing my window and scrolling to remove the sun from view) adds nothing.woops, forgot to put oppose in here.say1988
- Oppose. It's kind of nice, but it's a little too small, has a sloping horizon, and as per the comments above, doesn't really illustrate much. Enochlau 11:15, 15 September 2005 (UTC)
