How Qantas Ferried an Engine on the Wing of a 747

Seeing a 747 with 5 engines reminds me of seeing GE's N747GE testbed aircraft in Mojave, which usually flew with a odd engine configurations. I can't remember if they used the 5th pylon at all and most pictures show an experimental engine on the inboard pylon. Sometimes a very large engine[1], sometimes a small one[2].

One time they tried to ferry the aircraft from Mojave to Victorville with only three engines (they must have removed the experimental engine for whatever reason). They attempted the take-off but had to abort. It was quite a sight anyways. They went back to the hangar and we saw it fly away with four engines a few days later.

GE now has a second 747 to play with.[3]

I'm guessing they would never use a 5th pylon when engine 2 is missing and replaced by a potentially misbehaving or inoperable test engine. The 5th pylon could never accommodate a running engine since it's just an external cargo mount, not a full blown engine mount with all the necessary connections.
