If you set up and fly any instrument approach....
And the (sudden or not) weather at minimums prevents visual acquisition of the runway environment and landing...
THENCE --
The published missed approach procedure or verbal missed approach instructions yield the next appropriate response from the flight crew.
(1) Fly the procedure as briefed... safely back into the sky...
(2) Hold as needed at a safe fix & altitude...
Get new weather... wait for better weather
(3) Select a precision approach with lower ceiling/visibility requirements -- as I suggested earlier...
...Or...
(4) Proceed to an acceptable alternate airport and land SAFELY.
****************
Any all of those listed options--correctly decided and flown...
... PREVENT these types of accidents.
*************
The weather... including faulty weather reporting....
(If that is the case)...)
Should not deceive or induce a professional crew to make mistakes with these tragic results.
Just my (retired) professional opinion...
