Kalitta's operation is not so bad, all things considered.
However, when he acquired many of the BA -200 TriStars and converted 'em to freighters, things started to run downhill is a rather substantial way, in the maintenance department.
Why?
Quite simply, Connie would absolutely not listen to folks who knew better.
I asked him personally whether he intended to send any of his maintenance supervisors to RollsRoyce for training, his reply was "we have been maintaining JT3's here for a long time, a jet engine is a jet engine, my guys don''t need any training."
Big mistake, as he soon found out.
