I've seen this sort of thing before, Sam. It is normally the result of enthusiasm for a theme overtaking common sense and eucation. BTW , You may recall. I worked for BOC Industrial Gasses for a number of years and was trained at their Morden research facility.How could they have left off the words "air tight" in that sentence?As you and Darren C point out, if a compartment is NOT airtight, there could be no implosion because there could not be a differential between inside and outside pressures. The trapped air will simply compress with depth. I don't think there would be any visible air left down at 25,000psi. Like a can of soda (or pop as it is sometimes called) the gas will likely dissolve in the liquid never to be seen again.
