It is helped by the jounalist actually being able to talk to the divers themselves. Makes it all clearer. I must say having been strapped in a stretcher but just in a swimming pool with a Kirby Morgan on it is frightening. The CDG were trialling this rescue technique when I joined the CDG in 1980. The first cave trial also ended in a near disaster but valuable lessons were learnt although this, as far as I am aware, is the first time the technique has been used in a genuine rescue situation. At the time of the pool trial I felt complete loss of control. You have to have great trust in your rescuers. They did a superb job in just about the worse conditions to conduct such a rescue. I think the Mendip contingent might have had an advantage as some of the sumps here replicate those conditions plus they are, of course, cold!
