So why were these people, that had been so obviously neglegent, prosecuted?
Is there a word missing from this sentence?
whilst it may be the way of the modern world to have RTSA exclusively manned by engineers - that stops working when they make decisions about piloty things because they think they know better and won't ask an operator. That goes for aircraft configuration, role equipment, avionics and general ergonomic layouts of cockpits.
This situation is nothing new - see the constant battles between Bill Waterton and the engineers at Gloster. I accept that Gloster were the OEM rather than RTSA equivalent, but it's a similar idea.
