I can't believe Boeing is being sued.
Having worked there in 2004, I am more than aware of the common practice to disregard ANY law, not fix ANY problem, and have completely unqualified people flying the aircraft.
Boeing is being sued because they have "deep pockets" and will respect legal rulings against them, whereas even if a court rules that Orient Air is liable, getting any money out of them will no doubt prove very difficult. However, if you do have information relevant to the inquiry i do hope you will pass it on to the investigators, (and the lawyers) as this is the only way there is a chance of things improving.
