Another tale relating to Jack's DC9 endorsement ... he was having a problem here and there (apparently the TAA box was somewhere between dreadful and atrocious - I never had a drive of it so I can only relate second hand tales). Then came the standby power/instruments work .. Jack came into IPEC after that session with a grin from ear to ear ... "Mate, it flies just like a real aeroplane". Thereafter, it was plain sailing for good chap.
