Can you post some info to support this?
No I can't. If you read my post it is full of question marks. What I'm saying, is it aircraft ageing that is causing these mid air breakups? In other words, metal fatigue? Or is it poor design of the spar that promotes corrosion? Maybe flying in inappropriate conditions. Most of the inflight breakups that I read about are aircraft being torn apart in TS.
Again you need to supply your "aging aircraft breaking up" it is NOT HAPPENING.
No I don't. I'm asking questions based on what I read and thinking, doesn't sound right to me.
