Hanuman

Just had a doubt so thought of asking here... as far as i remember from the stories that my grandmother used to tell me from ramayan, Hanuman was cursed by a saint in childhood that he would not be able to fly but after he apologized for his mischief, the saint said that he will forget his powers and will only be able to fly when someone would remind him about it and i think he was reminded about his powers by Jamvant.
