This. For me, one of the more difficult type of engineers to work with aren't people low in tech skills or other traditional lacking, but engineers who can't deal with failings generated by other people, in a rational and civilised manner. 

Anyone building anything of modicum importance is going to fail. Moreover, failures can be institutional, i.e any process or lack of process, which significantly increases the chances of failure. These have to be dealt with at an institutional level. If the failure is personal, I.e caused by traits specific to the person, can it be resolved by having a better feedback loop. Many reasons to be angry but very few to express it in a confrontational manner. I have many brilliant friends I wouldn’t work with for the above reason.
