Yes, the US Air Force decided to make a little surprise for the Croke Park Classic between Penn State and UCF.
Apparently, the F-16s - there were two of them - soared over Croke Park, just as the American national anthem was finishing.
Because what better way to salute your nationality by screaming fighter jets hitting near supersonic speeds, right?
