If an image works well creatively in black and white it may be considered and the shot above of Tim's is one which demonstrates that well. The subject is not appropriate but the treatment is, totally, and it remains one of my favourite photos on the site.
Couldn't say it better.
The advice I would add -- not just for black and white but often for photography in general -- is: Think like a photo editor. Think like you're selecting photos for a magazine or a newspaper story. In the case of Tobias' LH
321 shot, you could totally imagine the photo running under a headline that says something like, "Lufthansa Brings Back The 1950s for a Day". The black and white is pertinent in that retro / nostalgic context.
As Mick notes, Tim's shot is black and white for purely artistic reasons, and once again, if I were a photo editor I would totally run it in B&W; it fits the essential, design-y feeling of the image. Pure form stripped of color, yet also conveying emotion. Imagine it in color: it would be a pretty unexceptional shot. And quite possibly a rejection for dark on this site
In other words, Don't do something cool because Photoshop lets you do it. Do it because you could explain convincingly to a hypothetical photo editor, from a creative point of view, why you think that shot should be the way you decided.
