i assume you can prove this claim that i am not an engineer designing aero engines
For the avoidance of doubt, I'd like to make it clear that it wasn't me who made that claim about you.
But
you certainly made this one, when addressing
me:
So to say you clearly have a background in the subject when all you rely on is google is a bit rich and highly insulting to those of that rely do have a background in aeronautical engineering.
Remind me again, who exactly is being "highly insulting" ?
Pot ? Kettle ? Black ?
