Some of the biggest acts in the sky will be available all weekend long at the Florida International Air Show at the Charlotte County Airport.

The show starts 9 a.m. Saturday, but crowds gathered as early as Friday afternoon to watch stunt pilots warm up.

"I like things that go 'vroom vroom,'" said spectator Mike Crain, "Starting with my snowmobile, and working up."

"It's fun to watch everything -- all the pretty planes," said Gib Loesel, who looked on with his wife.

Friday's biggest spectacle was the U.S. Airforce Thunderbirds, as the flight team practiced flying in formation.

"To see that kind of precision flying that close together, it takes a lot," said Al Dion, another spectator. "You've got to be young at heart to do that."

The 34th Annual Florida International Air Show is open from 9 a.m. To 5 p.m. Mar. 29-30.  Tickets cost $20 for adults.  Admission is free for childen 5 and younger.
