I came very late to this party but I enjoyed listening to "Interview on the Boeing 747, the Trident, VC10, One Eleven & the Boeing 727".
One thing that puzzled me was the multiple references to "incidence" when Davies appeared to be describing "angle of attack". In the terminology I'm familiar with "incidence" is fixed at aircraft design and describes the angle between chord and LFD. Has the terminology changed since these interviews were conducted?
