Have you noticed the various pax falling over themselves trying NOT to claim kudos for the rescue ? Everyone`s commented except the actual dive team.

The port tunnel often gives me panics attack
Just re read this thread.
You`re right Octy, sedatives and diving is a no go, but there was no way the kids would have remained calm and become a danger to both themselves and the escorting diver.
However, the masks they used on the kids were what`s called positive pressure full face masks, which means there`s a constant flow of air into the mask as opposed to a demand valve variant. The demand valve does exactly what it says, it delivers air ONLY when the diver inhales. As the kids were sedated and breathing softly, the demand valve variant may have suffocated them.
The positive pressure FFM also has the bonus of helping push water out of the mask which the rescue divers couldn`t do on a demand valve mask.
