A common complaint about “disruptor” types is that they are entirely cavalier about tossing aside established practice without establishing whether or not it’s established for a bloody good reason.
A phrase often used by critics of these people is that safety standards and engineering regulations are “written in blood”.
I understand one of the people currently trapped in the “Fred in a very expensive shed” submarine is the man responsible for building the thing with obvious disdain for safety and engineering regs.
Tl;dr: fuck around and find out.
@goatsarah It's the "teenage son" that boils my piss. take all the risks you want for yourself and your rich mates, but taking a teenager into what can be fairly described as a rickety deathtrap? No.
