In 1988 for the Bi Centennial celebrations, QF wet leased a B747 100 from Tower Air, A B747 (100?) from Aer Lingus and a DC10F from Martinair.
The agreement with the QF pilots was for the flying for the pax aircraft to revert to QF as soon as possible, which it did.However there was no such agreement for the freight and QF crews to this day have never got the lfreight back.
The moral of that story is don't be arrogant about the type of flying that is available and also get your agreements right at the beginning. Its too hard after the event. Tiger crews ,take note.
