This episode offers us to speak of something very new for this period. After all, this series was dedicated to science and new scientific discoveries, technologies. And it speaks here of holograms. I only heard about it for the first time - and not the last - in 1988 for MISSION IMPOSSIBLE TWENTY YEARS LATER - where it was used galore. But here, in 1974, yes it was a surprise for me to see now, in 2023, that it already existed. For the rest, this episode is OK, with a clumsy but good ending and another surprise, to find again the genuine female character who disappeared for a few episodes because she was hired for the big screen: LE MANS, co starring Steve McQueen.
