"unwieldy" and aesthetically inferior to Skyship One from the sequel Thunderbird 6 (1968). Alasdair Wilkins of io9 questions the design of Zero-X in that it is "not especially aerodynamic-looking". He also notes the craft's protracted introduction in Thunderbirds Are Go, judging the film's 10-minute opening launch sequence excessively long: "It's pretty much the Alpha and Omega of launch sequences ... a sequence that threatens to make 2001 [: A Space Odyssey] look like non-stop, thrill-a-minute action." He believes that with the attention to detail given to the various stages of the craft's assembly and take-off, these scenes constitute "launch sequence porn", elaborating: "It's a bunch of people effectively saying, 'Action? Characters? Humour? Nah, forget all that. We know what the people really want to see, and it's clearly the model-work.'" Hagerty states that notwithstanding the quality of Meddings' effects in this sequence, "there are limits to audience patience!" Mark Bould considers the sequence an example of the Anderson productions' "technophilic model-work".
