Don't worry Shadow- I spent several years living about three miles off the runway that had B-52s launching from it. I learned probably a little too young what the implications of white missiles are- I can't see a military aircraft without checking the pylons for that reason.
As for what he was doing... Check flight, probably.
Reminds me of the day of the US raid on Lybia
I was watching TV with Dad, and they were reporting from the UK on how the US was doing a show of force with their F-111s
I was watching the ordinance guys loading the F-111s in the background, and the takeoff footage, and I turned to Dad and said "show of force? Bull - those are LIVE GBUs - notice they aren't BLUE. We're bombing Lybia tonight, probably as we speak" - 30 minutes later, the President came on TV and announced the raid..
