This is the plot summary of All My Sons from IMDB
All My Sons tells the story of Joe Keller, a successful,
middle-aged, self-made man who has done a terrible and tragic
thing: during World War II, rushing to meet an order from
the Army, he knowingly sold them defective airplane parts
which later caused the planes to crash and killed 21 men.
He framed his business partner for this crime and engineered
his own exoneration; now, his son is about to marry the
partner's daughter, the affair is revisited, and his lie
of a life is unraveled.
Rang De Basanti has a similar plot line in which
Rajnath Singhania sold defective airplane parts to IAF MiG
planes. It crashes and kills one of his sons' friend's fiancé,
who was piloting the plane. But in order to save himself
he blames the crash to the pilot.
