"Fragrant Harbour A forum for the large number of
pilots (expats and locals) based with the various airlines in Hong Kong.
Air Traffic Controllers are also warmly welcomed into the forum."
Wasn't sure if you had read the header "N1 Vibs" , so thought I would cut and paste the Forum title for you.
I am sure there is a Forum for Engineers somewhere on the internet that would welcome you and am equally sure there wont be many Pilots there butting into a forum not actually meant for them.
