But we still operate the bellowing, thundering, 4-Conwayed VC10 of HMFC out of places like STN - and it hasn't had any noise reduction measures fitted since the 1960s.....
However, every time some Green Party tree-hugger in Tchermany whinges about said noise, one can't really quip "Shouldn't have lost then"! Quite how we continue to operate such deafening old things in the 21st century at civil airports I find difficult to understand....
