Behind Enemy Lines (2001)

Fighter navigator Chris Burnett wants out: he was looking for something more than the boring recon missions he's been flying. He finds himself flying the lone Christmas day mission over war-torn Bosnia. But when he talks pilot Stackhouse into flying slightly off-course to check out an interesting target, the two get shot down. Burnett is soon alone, trying to outrun a pursuing army, while commanding officer Reigert finds his rescue operation hamstrung by politics, forcing Burnett to run far out of his way.
