Actually DH had become a part of Hawker Siddeley(1960) before the Trident became reality. (1963), evil tounges suspected that the americans used quite a few of the for economical reasons leftover ideas for the trident, to develop the 727. Wich in turn where the reason the Trident really wasn't that comercially succsesful.
(Much as they took quite a bit of "inspiration" from the Canceled TSR2 to make the F-111.)
The main problem with the Trident was it's bad Vertical Speed performance wich caused ATC's with quite a few headaches, a proud european tradition that the Airbuses, most notably 330/340 series continues today.
European aircrafts do however have better mic-preamps for their PA.
Did anyone know BTW. that the flight control systems on Airbus A320/330/340's runs on 286-processors?
Doves where made by DeHavilland indeed!
Sorry about that, you got me triggered.
Oh...ehr..and don't forget Palestrina, he did a good job of keeping music on track back then in...1577?
