The engineers are not volunteers, like i said the CAA requires them to be proper professionals Volunteers cannot work on the aircraft, where they can be used they are. As to whether Mr Pleming is worth his salary i can't comment, But the chaps on the ground who work their socks off to keep 558 in the air are certainly worth theirs. I am a volunteer for the club/trust and i don't receive a penny for what i do. Every single expense the volunteers incur comes out of our own pockets, thats traveling, food, and accommodation. We do not get nor want a penny back.
