Regarding the recent accidents involving the 737 variant, l would also caution against hasty judgement and invite readers to (re-) acquaint themselves with the DC-10 accident at O'hare, American Airlines flight 191, which happened years ago.
From Wikipedia:
" The National Transportation Safety Board(NTSB) officials discovered that a maintenance procedure was the cause of the accident. American Airlines mechanics had removed the engine and its pylon as a unit, rather than removing the engine from the pylon, then removing the pylon from the wing, as recommended by McDonnell Douglas. The faulty procedure was done using a forklift, which resulted in inadvertent structural damage. It was subsequently discovered that this short-cut procedure, believed to save many man-hours on maintenance, was being used by three major airlines, although McDonnell Douglas had advised against it.[76]In November 1979, the Federal Aviation Administration (FAA) fined American Airlines $500,000 and Continental Airlines $100,000 for using this incorrect maintenance procedure.[76][78] "
Within hours ( If not minutes ) of this accident becoming public knowledge, widespread condemnations of the DC-10 and McDonnell Douglas had begun, which turned out to be largely unjustified as regarding this incident.
It may well turn out that Boeing are culpable in these accidents, but the disaster at O'hare serves as a reminder not to be hasty in our conclusions.
