Reason was TWA needed an engine for its plane in TLV and was given one or lent 1 whatever and now it was being ferried back.
So if TWA was able to do that why couldnt LY do it with whomever @ JFK, flight lands they put on a different engine and ferry the old one back on the flight back to TLV, if they wanted to fix it there rather then in NY
I believe the ability to ferry a spare engine on the 747 wing was an option that customers had to request, and most of the 747-400 operators did not choose that option. Also it could only be done for Pratt and Whitney or Rolls Royce engines but not GE engines.
