Most fatal RTA's also read "he/she didn't see the other vehicle" - or the "child didn't see the approaching bus or lorry " - in both these scenarios, they didn't see because they didn't look - or look properly and efficiently !! Or if they THOUGHT that they looked, they maybe didn't scan as well as they should have !! How oftern have we read of pilots who THINK that they did something in checks, but by habit they actually didn't - think about it, and maybe you'll see where I'm coming from - pardon the pun.
You seem to miss the point that if the lookout and drills are not as good as they should be, then there's not a snowball's chance in hell of seeing anything ! Look out and drills can be less than good even from the most experienced Squadron commanders big or small jets, whatever and whoever, - all I suggest is that something is clearly defective with the unacceptable recent losses.
