The famous Frecce Tricolori flew over the city in a 10-jet formation with their signature green, white and red smoke trails.
"It was really cool and a fun surprise that I wasn't expecting. And on such a nice day, it was a great surprise," said Carly Goldberg, of Rittenhouse Square.
"I thought it was fascinating. You usually don't see anything like that, but it's very nice to see that kind of stuff," added Aaron, of Center City.
Frecce Tricolori is the demonstration team of the Italian Air Force.
The precision team just recently had a performance at the New York International Air Show.
