Augmented Reality from World War Two?

From World War Two: Early Example of Augmented Reality, Virtual Reality?

As explained at http://www.bbc.co.uk/programmes/b05wdql2, these domes were used to train British gunners to fire at attacking German aircraft during World War Two by projecting films of incoming bombers and fighters onto the inside of the dome. The Langham Dome is the one surviving example of the many that were built during World War Two. To hit the target with a gun, trainees had to anticipate the flight path and hit that path, since firing directly at the plane would miss the target by the time the shell was fired.
