I agree with you in some respects (however comma) but the system has to be flexible enough to deal with all sorts of investigations worldwide, possibly in combat zones.
One example would be the Tornado Mid-Air over Canada in the early '90's which resulted in one aircraft lost and another badly damaged. The Pilot of the Tornado that hit his leader had a wonderful excuse - he did not realise that he was supposed to wear his newly prescribed "Corrective Flying Spectacles" whilst flying an aeroplane. I wonder what he thought they were for?
The damaged (but flyable) Tornado was diverted to a distant small Civil Field without escort whilst the crew that had bailed out were left in a lake in their dinghies for about 12 hours until the CAF managed to rescue them by flying boat. The rest of the formation carried on regardless!!!
I believe there was quite a queue outside CinC STC's office awaiting one sided interviews after the BOI was completed.
