I actually did see that program in Hong Kong about six months ago and they did pressurise it to a normal differential pressure an aircraft of its type would experience at cruise. I had no problem with their experiment or its conclusion. If you guys have experience with pressurisation you will know from the limitations section of your FCOM or Pilots Operating Handbook that the limitation on the pressure vessel, i.e. the fuselage is “Differential Pressure” not what the outside pressure is.
