Now you are mixing up causal and contributing factors. The wx wasn’t a causal factor a shitty wx reporting system isn’t a causal factor poor tower/ATC instructions that don’t result in a midair colission during IMC aren’t causal factors. Apparent poor crew coordination and ineptitude are, absent new developments. A pilot crashing a functional plane is to blame, always.
I really wasn't trying to
"mix CASUAL and CONTRIBUTING Factors".
As a matter of fact, I don't recall hearing the term
"CASUAL FACTOR" before,
but I've been retired from air traffic control since 2005, and with age comes forgetfulness.
But my primary concern is for
the safety of pilots, passengers, and people on the ground.
"Apparent poor crew coordination and ineptitude are, absent new developments [, to blame ].
A pilot crashing a functional plane is to blame,
I don't disagree with you, there.
But how much is due to "crew rest" and "pilot fatigue" ?
After all, according to
NTSB reports,
"Their flight duty began Tuesday evening at 9:30 p.m. in Rockford, Ill.
The pair then flew to Peoria, Ill., Louisville, Ky., then headed for Birmingham."
Since UPS 1354 crashed just after (04:47AM BHM time)
05:47AM Eastern Daylight Savings Time,
he/she had been on duty for a little over 8 hours 17 minutes,
and were in the wee hours of the morning,when a human beings' body is really fighting the "natural desire and NEED to sleep" ?
