I agree it does look better in B&W. Shows up much more detail. Like Sally and Susan I never noticed the plane in the colour version. What I did notice was the flags but in this one they do not grab your attention the same.
Fab POV Pam and I like your processing for the building and that plane up there too. The sky looks like a bit tempestuous though as though a huge storm is coming. I would like it without the grey cloud above the white. It's a cracking shot!
