I'm struggling to think of a major modern programme, military or civil, inteh west that has NOT had major issues in the last 25 years.
Even Mr B can't convert a 767 into a tanker, which most people would think would have been straight vanilla, without massive problems (some of which are still unresolved)
A real problem for all western industries appears to be the engine manufacturers these days - - they all seem to have problems right now
