Not sure if this is the appropriate way to handle this but here is @FloofahNZ@lemmy.nz'a comment. If they want to repost it themselves I can delete this one:
I’d guess the contractors were not properly instructed. This brings a point, who were the contractors working on this? Did they have any relevant experience, or were they simply casual labour?
I’d expect all procedures to be fully documented and importantly regimented into crews. But seemingly not in this case, how the hell could this happen?
No need to repost it, thanks. There’s something seriously amiss in their operating procedures and their ground crew management imo. How could even un-specialised contractors think it ok to remove more than a few nuts at a time?
Someone rushing them? Or just a misunderstanding of the physics of the situation. It's probably a good argument for why you need to teach people the reason for procedures, instead of only telling them the procedure.
