We're debating with a person who claims to be an engineer designing aero engines yet writes such nonsense
I read this in the context that an engineer is writing something that, to the author of the above quote, didn't make a lot of sense for someone who is suppose to be an engineer...not the way you have seen it which I assume is the author saying that because what you wrote didn't make sense to him you cannot be an engineer.
Much like someone saying to me that they can't believe I claim to be pilot if I did a landing like that - They're not claiming I'm lying about being a pilot, they're just claiming that as a pilot they can't believe I actually did a landing like that!
And off the record I nail every landing - on the record though...
