Franzl - even if PIC expected barometric readouts, then after 100 and below he would anyway have been in an "area" mandating a go around - so he couldn't have expected it later on.
I wonder what kind of duty he had during this approach.
Most unfortunately the entire crew probably wondered too, as there were no SOPs, and CRM (briefing) was non-existent.
Also, you try to paint it as "sh*t happens", if I understand you correctly. But since Jan 2008, Polish Air Force had 4 fatal accidents claiming lifes of around 130 people, all in perfectly flyable a/c, all due to same reasons - lack of training, bad procedures (which were being broken anyway), bad airmanship, etc. Additionaly to that other incidents - belly landing, or exposing C130 to excessive g's during approach in Afghanistan, due to incorrect maneuvers, resulting in it not flying any more. So the causes are systematic, not simply "something went wrong this time".
