As an ex QF employee in the sixties, based in Singapore; two very serious incidents occurred that I can not find any reference to. The first one involving a 707 night landing and go around on 02 at Paya Lebar Singapore, resulted in a rescue team of QF engineers patching up a severely damaged airframe due to a hard touch down on the nose gear. The aircraft was ferried back eventually to Sydney unpressurized for permanent repairs. The second was a jet upset over India en route to Singapore where a captain followed a toppling AH, disengaged the AP and and severely stressed the fuselage in an attempt to rectify a false attitude indication. I haven't read the book, nor am I inclined to do so but I'm certain these incidents remain unrecorded by the authors who may not have been borne yet in 1965.
