Whilst the divers gently punch you in the abdomen if they think that you’re not breathing out on the way up.
Actually once you got over the panic of being flooded whilst trapped in the chamber the escape trainer was quite good fun. The dunker ( initially at Vernon then VL) less so. !!!
No idea why the submarine service stopped it. Seemed like vital training to me.
