Why is the 5 upside down on the date 1953 in the design? Is this a miss print? No, this is not a miss print, this was at the request of the U.S. Air Force Thunderbirds. The #5 is painted upside down on jet #5 because it represents how the lead solo spends most of his time during an aerial demonstration which appears right-side-up for much of the routine.
