Think back to the Challenger Disaster and Richard Feynemans appendix to the report.
Management makes the false assumption that just because a LAME has never "saved a
VB aircraft from disaster" by finding a lethal defect on a morning walk around, that this is never going to happen.
Unfortunately statistics, as Feyneman famously pointed out, always win in the end.
99.9999999999999999999999999999999999999999% of the time a LAME check is a needless luxury.
Just pray you are not on the aircraft on the one time that it isn't.
