In 2002, Gerry Anderson explained how the vehicle's safety features were borne out of his "preoccupation" – demonstrated in various aspects of "Captain Scarlet" – "with things not being what they seemed ...With a flick of a switch the walls of these buildings would collapse to reveal this astonishing vehicle inside. I knew kids would find that exciting." He quickly regretted his decision to make the seats rear-facing, commenting: " ... we began to realise that the audience was going to say, 'Why are these people facing backwards?' So we wrote an explanation into the first script. Then I realised that not everyone would have seen that episode so we had to put explanations in again and again." The rear-facing system is well received by commentators Jim Sangster and Paul Condon, who praise Anderson's innovation and credit the feature as a "work of genius".
