The early part of the program mentions the McDonnell Douglas management method; those of us who flew the DC10 will remember the design philosophy influenced by accountants that led to the Chicago, Paris and Sioux City accidents. The hydraulic system and slat system designs along with the supposedly non standard engine maintenance procedures. The most shocking and crooked part was that the Turkish crash was initially blamed on a Paris mechanic eventually it was discovered that a mandatory modification had not been carried out but MD falsified the work and it’s inspection paperwork.
IIRC the MD11 was certified on the back of the DC10 as a full certification process would have involved substantial modification and expense. There is also the question as to how much Kapton and the insulation materials were part of the SR111 loss.
