Amazingly enough I don't think new regulations would have helped here.
I read the transcript and noticed some things that impressed me. Things that indicate they were not that tired. They were up for the approach.
They actually identified the Localizer/DME using the morse code.
They picked up on a similar call sign plane.
They noticed their plane was vectored HIGH. And complained about it (as pilots do inside the cockpit instead of saying: Approach, that was a SHIRTY vector, how about another one on altitude 5miles outside the FAF?)
Something about starting their day at 9pm at night, scheduled to land before 6 am is something like a 9 hour duty day. MIND YOU it is all ''back of the clock" flying. But many of us have worked 16 hour duty days under the old regs.
I think the instrument discipline should be maintained even with a runway in sight call (was there a callout at imtoy?)
Two pilots died. This is sad.Over 50 years ago many in the industry said every runway served by a jet transport should have an ILS.
