I watched a rather bloody experiment originally shown on the TV programme mythbusters a couple of days ago.
The old fashioned diving suit was filled with a pigs carcass with flesh, bones and entrails and depressurised . It was slower than nanoseconds they talk about and not pretty.
Some boff did an animated version of the submersible imploding and showed a much faster merciful demise. :-). I suppose that is supposed to give some comfort to NOK.

To get some idea of what happened to those in the Titan, you could take a look at what happened in a diving rig working from the “Byford Dolphin” drilling platform. This is somewhat the reverse of what happened last week. “Saturation” divers were living and working at a pressure of 9 bar when their rig was accidentally depressurised. Caution for the faint-hearted – some of this makes grizzly reading:

The Byford Dolphin incident resulted from a rapid decompression from nine to one bar. The Titan incident involved a pressure change of more than forty times that magnitude. When it imploded, the air and everything else inside it were suddenly exposed to pressure approaching 400 bar (that is, 400 times normal atmospheric pressure). The air would have been superheated by this compression (think how warm the end of a bicycle pump gets) and the spaces in the humans’ bodies – many full of air and other gases - would have been similarly crushed.
The good news is that all this probably happened faster than the signals from the victims’ senses could reach their brain. They would have had no notice of their impending doom.

This shows the merciful demise of an imploded submersible and its occupants.

How do the smug experts know how "instantaneous" it was, nobody ever having survived such an event to tell the tale. The comparison with a balloon is nonsense - a balloon is made up from extremely flexible stretched material - the sub hull may well have creaked and cracked before finally giving way.
OK, Karma for the CEO, but what about the poor lad whose father forced him along - his terror doesn't bear thinking about.

Perhaps it's a cultural thing in India. I recall taking my young grandchildren to a large play park near us called HobbleDown near Epsom. There were high wire rope walks which the two girls wanted to try. They had safety harnesses but the older girl decided she had enough and was rescued by the young man supervising.The younger one scampered along the wire like a squirrel.
There were two Indian looking Asian families in the queue behind us and one father watched his young son negotiate the wire without to much difficulty and the pride on his father' face was obvious. The second young lad started but decided not to go further and wanted to step back on the start platform. The father screamed and exhorted him to get on the wire and show how brave he was. It was excruciating to watch and the poor lad was screaming in fear. It was no more than bullying IMO but to the Father he had to save face with his friend.
The 19year old in the submersible seemed to be in a similar position but felt he had to please his father. Shame and Sad.
