Mukesh dreams of owning a car one day but doesn't dream of flying a plane because his aspirations are limited by the environment in which he lives. Mukesh and his family belong to a community of "bangle-makers" who are excluded from mainstream society and denied access to education, healthcare, and other basic amenities.
Mukesh has never been to school and his desire to own a car reflects his yearning for a sense of dignity, mobility, and social status that he lacks in his current circumstances.
Flying a plane is an ambition that requires a level of education, skills, and resources that are beyond Mukesh's reach. He has never seen an airplane, let alone flown in one, and doesn't have the knowledge or means to pursue such a goal. Mukesh's dreams are thus bounded by the realities of his social and economic situation, and he finds solace in imagining a more modest but still meaningful future for himself.
