Way back in 1973 when I did my Area Procedural Rating oral board exam, the last question I was asked by the Chairman (the famous Malcolm Lucas) was " why do we bother teaching this stuff when we're going for an all radar setup at the Centres ?" I said something along the lines of "because nobody believes Tels Engineers who say it'll never fail !" which caused some mirth on the Board.
As the French say (rough translation) " the more things change, the more they stay the same!"
