Trish,
I certainly don't want to be accused of being persnickity here, but I'm not sure we mean the same thing when we say "loss of control". If the vertical fin and engines fall off, I guess you're "out of control" but I don't see that pilot behavior or emotions at that point have much to do with the "cause" of the accident.
The only part 121 accident that I can think of off the top of my head that involves "loss of control" and might (and I use the word might here advisedly) have been avoided by different inputs by the pilots is the Airborne Express crash in the late 90s. After reading that transcript, panic is the last word that comes to mind. In fact, I was almost nonplussed by the crew's calm.
Perhaps if you gave us an idea of what accidents you're thinking of?
Best regards,
TRF
