The 737 accident you mention sounds very much like the crash of the South China Airlines B737-300 in
1992 - although it didn't occur during an attempted go-around.
To the best of my recollection, the accident report didn't say anything about alcohol.
I assume you had 'inside information'?
The Colorado crash sounds like the Jetranger crash even longer ago in December
1982 when the (single) pilot of a news helicopter pressed on at night in atrocious weather (snow & fog) in mountainous terrain.
"drunk on his ass"
The pilot's alcohol level (some hours later) was 0.093%
(I doubt if it would be possible to fly a light helicopter while 'drunk on your ass'.
)
