The aircraft in the film are all authentic aircraft used in the 1971 war against Pakistan. These include MiG-21s, Gnats, Hunters and Su-7s. Some of these aircraft were also flown by war veterans such as Samar Bikram Shah (2 kills) and Manbir Singh.
Produced by Dev Anand cousin Ravi Anand.
Chetan Anand shot alot of scenes with Amjad Khan. But during the editing, he shortened his role to almost nothing. The film flopped and Amjad Khan was not noticed.
Navin Nischol was offered the film but unable to sign it due to some contract situation with Mohan Segal.
Parikshit Sahni signed the film because Raaj Kumar insisted he sign the role. Raaj Kumar was fond of Balraj Sahni and wanted Balraj's son to be part of the film. Parikshit first down the offer than finally agreed.
