We have had this discussion two pages up already. Of course there are plenty of examples of pressurisation related accidents that were not or could not be prevented by a second pilot on board. But there are many more happy outcomes due to an additional crewmenber. Not to talk about non-pressurisation related incidents that can only be recovered by a second pilot. Or, as you write, some kind of technical solution. There are some newer planes which can have this feature installed (e.g. Beechcraft Denali, Piper M600, Cirrus Vision Jet) but retrofitting an older aicraft like this C560 here is going to be a lot more expensive - if possible at all - than to pay for a second pilot for the next 20 years.
