When I watched RSRD I saw Nisgeis' 3D TDC Radar Range Unit! Amazing! I am still wondering how the directors were able to recreate a prototype of Nisgeis' mod and insert it into a movie made over 50 years ago? Nisgeis hadn't created the mod yet! At least the directors weren't dumb enough to have the Clark Gable or Kirk Douglas manipulate aaronblood's MOBO so they could outflank the Japanese submarine. Everyone would have caught that mistake, no doubt about it.
