More on the All You Need Is Cash Clues

In my July 16, 2010 post, I discussed the PID clues in the satirical film about The Beatles, All You Need Is Cash.  To clarify two points:  1.)  When they said that Stig was rumored to have died in a flash fire at a water bed shop, I contend they were referring to a hyperbaric oxygen chamber (see my post of May 7, 2010.)     The flash fire part of the clue would be the fire risk in oxygen chambers caused by the volatility of pure oxygen.  In a Times of London article of June 21, 1968, they discuss a study made by the Royal Air Force Institute of Aviation Medicine where "scientists ignited more than 100 full-scale dummies or dead pigs in various oxygen pressures to determine the characteristics of a clothing fire."  The scientists found:
    "Men usually take between five and 20 seconds to respond to an emergency, and conventional
     extinguisher systems take about two seconds to come into operation.  Within this time, the experiments
     suggest, a man working in a typical oxygen-rich environment and clothed in a denim overall would
     suffer third degree burns over at least half his body."
A man trapped in a hyperbaric oxygen bed could die.

2.)  I found an interesting amplification on the Limpet mine reference in the film.  According to the book, Underwater Swimming by George F. Brookes and Robert B. Matkin (1962), "wartime 'frogmen' had a self-contained diving apparatus . . . but this apparatus was complicated to use, required skilled maintenance and employed pure oxygen."  Like the Lotus hyperbaric oxygen bed.
