Cathay recruited from BA for their expertise
ASFKAP. Of course Cathay Pacific Airways recruited from BA. They also recruited from Qantas and Air New Zealand, as well as from other sources, not just because of any L1011 expertise, but to grow their engineering capacity as the airline fleet grew. Cathay took delivery of their first L1011 only a year after BA took delivery of their first example of type, so just how much more expertise and experience than Cathay, on the L1011, did BA have? Cathay became one of the largest non-USA based operators of the type and through their engineering arm HEACO became an approved RB-211 overhaul facility and gained major L-1011 heavy servicing contracts from other operators. BTW, BA were among those who sent their B747's to HEACO for the Section 41 Inspections and Mods. And in defence of 411A, the Tristar is a great example of advancement for its time and did not, as you claim, require two ground engineers to be carried to keep it going. Tech delays were a rarity with Cathay Pacific and no ground engineers were carried, just a crew who knew their aircraft technically as well as operationally.
