In the film, Kishan (Amitabh Bachchan) and Bishan (Amjad Khan) are good friends, who get separated in childhood.

Years later when Bishan returns to village to take Kishan to the city, there is a scene where he teaches Kishan hang gliding. In that scene, Amitabh takes off wearing a black helmet. But once he is in the sky, he is seen in a white helmet!

Does that mean he had time to change helmets in the sky?
