- the AD's regarding fan blade attachment on the CFM56 engines have been around for so long that there should be a great deal of awareness around about this issue, to the extent that this shouldn't be an issue anymore;
- the two Southwest aircraft which had uncontained engine failures were 10-15 years old, and the present aircraft is only about 3 years old;
- from a statistical point of view since several years there is a huge amount of B737's with these engines around, logging a tremendous amount of flying hours, yet such a catastrophic engine failure has never happened....
