Translation Clip "a" : S: Here is the plug-door that will seal the narrow tunnel before creating the outer space conditions inside the containment room. Ionic thrusters require such conditions to be operational. Clip "b" : S: Under the dome, there is also a similar narrow tunnel with a plug-door system. ... Go! Crawl into that narrow tunnel. S: Ho! Yes, Professor! Clip "c" : S: You will find a larger tunnel that connects the confinement room of the tower to the prototype of an ionic mirror that is built with an untested new type of material. The same material will be used for building the Hyprop. You will have to test this ionic mirror. Clip "d" : T: Strong wind this tunnel. Clip "e" : T: Dirty! Clip "f" : T: It is empty, but dirty because of the renovations that are happening now. Clip "g" : T: A big cleanup will be required. Clip "h" : T: The vacuum will be maintained by 2 mechanical pumps, so noisy, then assisted by these red ionic pumps that looks like decorative disks. Liquid nitrogen will be injected between the inner wall and the outer wall of this confinement room, in order to cool everything to cryogenic temperatures of 70 Kelvin. Brrrrr!
