From the start, there're two victims: pilot Beeman's unseen death after the crashlanding and later Dexter (probably eaten by the self-reproduced mutated germ). The alien probe contains two labs: one column-like communication lab and one chemical lab. This column-lab is both a microscope and at the top of it, a circular hole lighthouse which sends various rays: to gas, to dry, to freeze—Dexter undergoes extreme cold—, the cut and swallow, to heat. Music supervisor John Caper Jr. uses again the "O.B.I.T." 's machine sound effect to announce an odd occurrence. In the same lab, we can watch an unknown alphabet on a plate and the display of geometric symbols (see "The Brain of Colonel Barham") to communicate via a hand-held button. Four passengers encounter a giant civilization but the analyzing lab is much too earthling to be real! To create the illusion of a giant-sized chemical lab, the editor blends two different scales of footages: one close-up of a lab and a master shot of the three characters who look at its direction—notice the power pylon from "The Borderland". Find for the last time, the decompression chamber from "Cold Hands, Warm Heart" that is recycled to check out a space map. For the anecdote: we can see the shadow of a microphone boom in the rear when Jefferson Rome and Amanda Frank talks in the communication lab during Act III. The core of the episode is a pamphlet on NASA's abuse of launching probe (see the Surveyor probe) and its aftermaths on alien civilizations: a reduction to the level of cases or guinea pigs. The reverse plot from "Wolf 359" whose main theme is the basic alien contact (as impossible as in "Cry of Silence") but a second-rate failure owing to its turnaround framework and featuring a giant microbe—which may have destroyed humanity as in "The Man Who Was Never Born" and looks like the cousin of the box creature from "Don't Open Till Doomsday" covered with a Luminoid's skin. The giant lab props are surrealistic. The three leads are cleaned up and dried inside a tube as Andrea Holm in "A Feasibility Study". The tube is a typical detail, reminiscent of the 1950's that is used to travel in two classic sci-fi films: "Forbidden Planet" and "This Island Earth". Peter Mark Richman is the last alumnus from season 1 who keeps his scientifical's background. Last but not the least, the explosion of the space probe is as cheap as the one from "Don't Open Till Doosmday". TV Analogy: the microbe will inticipate one mole monster from a "Star Trek" episode: "Devil in the Dark". Notes: Pay attention to the fact that two cinematographers share the same onscreen credits: Kenneth Peach which starts during the end of Daystar's season 1 and Fred J. Koenekamp, better known for his involvement in the espionage series: "The Man from U.N.C.L.E.". Actress Peggy Ann Gardner will be present in the now famous episode of "The Man from U.N.C.L.E.": "The Project Strigas Affair", along with David McCallum, William Shatner and Leonard Nimoy. Stuntman Janos Prohaska wears the costume of the giant-sized microbe named Mikie.
