It shouldn't require 7 pages of detailed scrutinization, and it wouldn't if a certain someone hadn't kept inventing new excuses to keep insisting that his hacked together google translated comprehension of Gongke's comments were correct.
Keeping this forum healthy is more important.
And yes, it could have just been a careless typo, but that seems unnecessarily speculative to me (it adds more information than is there, or is necessary), especially considering that this isn't the first time Gongke has made mention of other people seeing the nozzle even if they haven't seen the whole WS-15 before.
A simple careless typo or bad choices of words, are less speculative than trying to twist the language out of shape through 7 pages.
All languages have inherent grammatical logic. Contemporary Chinese doesn't have as many rigid grammar conventions, but that doesn't mean there are no common tendencies and rules.
As I have already mentioned earlier, native Chinese mostly don't use grammar. It is what it is. You need to explain a simple sentence with some 200 words of rules, that the native Chinese don't even use, is only because, you don't know the language well enough to really understand.
