Did I blame the pilot? First read the sentences carefully. I wrote the reasons which might be the reasons for planes crashes. 

The engineers of Aviation industries are the ones who knows about the condition of the planes.
I don't know how much information the pilots get or know about the condition of the planes before flying. Despite the knowledge of broken planes, if the pilots take risk either under pressure or at their own self confidence, then we cannot do anything unless such pilots fly planes.

If the foreign educated pilots cannot do anything, then you all think deeply.
