A six-year-old girl and her three-year-old sister got a big surprise: their father who has been serving in the military.
The girls were chosen to help officially open Six Flags Great Escape in New York for the day, and look who was waiting to surprise them at the park.
Their dad, Sergeant Donald Chadwick, hid for a few hours to surprise his daughters.
Sergeant Chadwick has served in the air force for six years. He plans to take full advantage of this time he has with his family before he returns to duty in two weeks.
