Roffa, you now as well as I do that pilots sit in an aluminium cigar tube with a bank of instruments obscuring most of their view and their awareness is limited to what they get from their instruments and computer and what they hear on the radio or exceptionally get told by TCAS. Is it so difficult to understand why they do not easily believe that their safety was compromised unless they are actually knocked off their perch at the time or are at the very least shaken or stirred by what they discover later?
So that mostly leaves it to you guys and girls to call - and "It's no big deal" isn't the kind of call that reassures us all.
