Angels of Light - Beyond the Veil

A cocky, wisecracking, commercial airline pilot has a surreptitious, lifelong relationship with the apparition of a dead relative, killed decades earlier in a military plane crash. When the apparition urges the pilot to solve the mystery of that crash, government censorship and stonewalling ensues, eventually surmounted by confidential information provided by entities disguised as the pilot's dead relative and murdered comrades.
