I did not mean to infer that they would have been breathing 100% oxygen all the way up from 235 feet but that at some point in their decompression, they might do that to hasten the purge of nitrogen.

The DVD clearly shows that each diver began his dive with 4 tanks. Two in the standard position on their back and one on each side hanging from their buoyancy compensator.

The father and son team that died made deadly errors. Firstly, they couldn't afford to buy trimix so they dove using air. Secondly, the son got trapped inside the sub while the father was outside. He finally went in looking for his son, found and freed him but both exited the sub from a different point from where they went in and where they'd left their extra tanks. Nitrogen narcosis set in because they were breathing air vs. trimix and in a stressful situation and they couldn't find their extra tanks. Almost out of air, they surfaced without decompressing and both died of the bends.
