I agree with you, when I was a child I lived right by Heathrow Airport, In the 60s piston aircraft were still very much part of the scene, Constellations, DC3s, 4s, 6s and 7s, The odd Stratocruiser, Convairs, Breguet Universals etc, they gradually faded out over the years, Then came the loud early Jets and Turboprops, Trident's VC-10s, B707s, DC-8s, Vanguards, Viscounts, Electras Argosys, they too are now more or less just ghosts of the past, These days it's just endless streams of identical vacuum cleaners! Progreass may be good, But I prefer real aeroplanes!
