As discussed on other threads, " would you like to take the airframe up immediately post maintenance ? " NO THANK YOU
My dad was an 'erk' (groundcrew) in the Far East during WW2. After the war had ended and things were a little less frenetic they spent a lot of time giving war-weary aircraft a thorough going over.
The pilots would always make the ground crew come up with them on the first flight after the overhaul. "If I'm going to prang, you're coming down with me." (Obviously not with Spits etc).
Dad loved it and logged many pax hours pottering over the jungles of Malaya and Burma.
