features an elaborate exhaust facility that enables the engines of jet aircraft such as the F-16 to be tested with minimal interruption to local residents and livestock. Hush House is situated south of the runway, towards the eastern edge of the site. Cost In total, the two programmes are together rumoured to have cost around £4.5M GBP to produce, including prize payouts, the 6-month audition process, set making, staff salaries, and profits for Zeppotron. The high cost fuelled speculation and rumours about further shows and the possibility of the producers performing a double-bluff in the future (Virgin Galactic is likely to offer initial space tourist flights for £100,000). Psychological aspect The show consistently raised the issue of how an immersive illusion can convince average people over a period of time, especially when reinforced as part of a group of believers – especially when this includes men in white coats and other authority figures. Outsiders (in this case, the viewers) see the hoax as laughable, yet 'inside' the Cadets have been slowly lulled into (as Vaughan stated) "what is, in effect, an alternative universe."

I would wake up at night and think there were cameras in the corner of the room. It was quite disturbing". Parallels can be drawn to the supposed 'group experiment' element of Big Brother which Space Cadets draws on, and in wider terms propaganda, subliminal advertising, and the consensus nature of reality.

Several episodes of Mission: Impossible staged similar "false journeys," which attempted to convince gullible victims of some of the confidence games around which the methods of accomplishing the missions were centred that they were supposedly in transit when, in reality, they were actually not moving or going anywhere at all. 'Double hoax' theory As the attention to detail in the hoaxed environment became clear, some viewers expressed suspicions – in particular on Channel
