It was similar in the UK in the good old days ...... man watching each engine & each wing tip checked along with plenty of other people checking & a whistle if anything didn’t look right ..... probably can’t have that these days as someone would complain about the noise....... people on the aircraft were aeronautical trained!!
Love the name by the way musthavagander ..... we used to have some called musthavapiss. When the work was being dished out!
