Noisy Tridents...
I grew up in Kew, under the Heathrow approach. We lived at just that point on the approach where the Tridents would lower the undercarriage...and the autothrottle would compensate for the added drag...and we got the benefit of the added noise! My neighbour and school chum went off to Hamble and thence to BEA and Tridents....a few years later I was at Linton on Ouse and JPs.
