Last Saturday (11/1/08) I was talking photos at ILG when I noticed three heavy contrails in close proximity. Through my telephoto, I could make out three aircraft that appeared to be C-5s flying in close trail at what I'd guess to be FL 30.
I've never seen anything to suggest that C-5s fly in formation. I actually got the impression that it's pretty unusual anymore for military transports or even bombers to fly close proximity to one another.
