This is a picture of a toy - what's so great about that? — Preceding unsigned comment added by 88.105.17.83 (talk)

  • This aircraft is very real. The camera is placed in a bed of pebbles and the persons next to the aircraft are blurred due to long exposure time, both adding to the illusion of the aircraft being a scale model. Ma.rkus.nl (talk) 20:23, 19 June 2008 (UTC)Reply


Bad ass images of ass kicking war machines like this make me badly want to support the war again as I did when I was a naive youngster. :( —Preceding unsigned comment added by 63.245.144.68 (talk) 02:09, 12 November 2008 (UTC)Reply

  • I also wish it wasn't sitting there, but it's a beautiful aircraft and photograph.


Why are the ends of the rotors glowing? Are they just reflective, do they have lights, or has this been changed on the photo? --195.194.120.37 (talk) 13:12, 12 November 2008 (UTC)Reply

Looks really fakey. maybe that's just me though. —Preceding unsigned comment added by 67.53.251.171 (talk) 14:51, 12 November 2008 (UTC)Reply

What's the deal with the guy 3rd from the aircraft? He looks strangely out of proportion with the other dudes. Bikingshaun (talk) 16:29, 12 November 2008 (UTC)Reply

He also appears to be mostly naked and wearing only briefs. I think that means this is a combat mission. Tempshill (talk) 22:32, 12 November 2008 (UTC)Reply
I highly doubt that he is that fat and his skin has som many creases, looks like a light brown uniform. This really looks like a compat mission due to the large hole in the winshield. Pokeman (talk) 22:57, 12 November 2008 (UTC)Reply

This is an amazing picture, although what is the green spinning around with blades?Nick (talk) 19:59, 12 November 2008 (UTC)Reply

Yes, this should be explained. Tempshill (talk) 22:32, 12 November 2008 (UTC)Reply
My first guess would be real lights that can be turned on to show where the blade edges are (to prevent accedental contact). It looks quite real in the full resolution picture, the line color is inconsitant, it splits into two lines at a couple of points, and is affected by the red light accurately.

Glowing Rotor Circles

edit

I know it's been quite some time since anyone talked about this; but I believe I figured out the source of the effect, and thought others might be interested. Based on a quick look around it seems to be caused by corona discharge, due to sand particles in the air striking the rotor blades (see the article on helicopter rotors). It appears to have been informally named the Kopp-Etchells effect. Very neat stuff! —Preceding unsigned comment added by Aidolon (talkcontribs) 23:52, 7 March 2010 (UTC)Reply

The "Kopp-Etchells effect" looks quite different, with broader bands and many individual sparks being visible - see photos here. So I don't think that's what's shown in this image. (BTW, while that effect is sometimes called a "corona effect",[1] and its precise cause may not be known,[2] I gather it's not caused by corona discharge.) --Avenue (talk) 09:34, 12 June 2010 (UTC)Reply
Thanks for the info/corrections! --Aidolon (talk) 18:22, 13 November 2010 (UTC)Reply
NVG formation/collision avoidance lights!!
