I found it very unusual that the 'Delta' consultants for Koreans safety audit seemed to have such extensive knowledge of B747 operations since they had not operated any at the time for decades !
Yep, it's obvious that this was never written by Delta types or even Americans for that matter. We don't nickel and dime over the use of armrests and when to return the gear handle to off.
This document was for a while published on Alex Patterson's website, he mainly has views on the AFAP debacle of 1989 posted there.
Somehow the 'audit report' achieved urban legend status and was touted in some quarters as the actual summary of Delta's findings.
Delta did operate a couple of 747's in the 1970's as I recall. Were they leased from Pan Am, perhaps?
