MAC, now AMC (I think), seemed to always run on their own schedule.
I was always in SAC and on time meant ON TIME. If an aircraft had a mission take off time of 0900 the plane would taxi to the end of the runway, countdown the seconds and release brakes exactly at 0900. Mission planning was precise and it was mandatory everybody adhered to the exact timing...every day.
The only times things went haywire was when something broke and then many times heads rolled.
Going back and forth from CONUS as a unit was good.
Thinking about it, it was when we were on the tarmac with all our personal military gear waiting to load that it was bad. If we were in a terminal it was much better. Go figure.
