Knock at least an hour off that in a 74.
Was sitting on the ramp at Yokota AB (Tokyo) in my DC8 preparing to depart for Paya Labar AB (Singapore). A nearby C-17 loaded up and taxiied out about 20-30 minutes before we blocked out.
7+ hours later we're getting in the van to ride over to customs in Singapore and here comes that same C-17 taxiing up to the ramp!
