[Mrs. Bolton enters the gym to find her son and husband busy shooting hoops] ...
Mrs. Bolton: Boys? Did we really fly all this way to play more basketball?
[That transcript is from High School Musical 2006. You may want to watch the video here (about 1 minute) to know the context]
Does 'fly' in that sentence mean to move quickly into the air? By the way, I don't understand that question. What does Mrs. Bolton actually ask about?
