Maybe not. BUT, what's indesputable is that commercial airliners contribute significantly to cloud and haze cover. I like sunny days. I don't like hazy days. I don't like cloudy days. Sun makes me happy. So, anything that makes less sun makes me sad, irrespective of greenhouse effect (or lack thereof) OTOH, clouds are a great diffuser, and you don't get those blown out highlights and dark shadows on cloudy days... <vbg> cheers, frank -- "Sharpness is a bourgeois concept." -Henri Cartier-Bresson
