As you know there are many ways to safely operate an aircraft which all hinge on training standards...Monitored approaches can be flown in different ways.
With regard to the inquiry I discovered at the Sunderland Trident museum knees up a couple of years ago that there was a lot of potential testimony withheld. Particularly interesting were the two captains that took off around the same time. Key blocked the runway for approximately 5 mins according to them, one on the Viscount asked ATC for a block take off and got airborne before PI and the other waited and took off immediately afterwards. They both speculated at what an intolerable atmosphere there must have been.
I was recently threatened to be taken off from a site after I supported a fellow pensioner who had criticised what I perceived to be racist, misogynistic and Rule British Airways remarks wrt another Asian incident. The guy was our union rep and he accused me of a rant which it wasn’t; I scratched a nerve wrt the inquiry and his input.
Fortunately we have come a long way from those bullying days (to a degree).
