The 757 came from Ansett and it operated in conjunction (joint venture - JV) with DHL; CEO for DHL at the time became Head of Cargo for GF eventually before leaving to be CEO of Ethiopean Airlines.
The aircraft did BAH-SHJ-BRU if I remember correctly with the odd 'charter' or special flight - it took all the BCCI paper work/files to Europe from AUH for the court trial.
The aircraft was not designed for 'normal' cargo; the floor was not strengthened, it did not have a main deck bulk head of a type to allow dangerous goods either. It was an aircraft designed for the parcel services not your run of the mill general cargo; thus it was a bit of a loss leader for GF and hence the pull out of the JV with DHL. DHL did of course make it work for them.
Another "worthy business plan" from the brains that ran (and some still do) the airline at the time.
