I think the official EU (read: bullshit ass-covering) explanation is that the warranty on Artoo's jets had expired by the time of the OT, forcing his CPU to lock them off, or something stupid like that.

I think they should be removed from the PT, not added to the OT. I thought they were ridiculous and, frankly, stupid.

I thought as a device it made sense, Artoo is an astrodroid, he has to work outside ships and the jets would come in handy for that and in that respect I don't mind it being introduced into the OT if and only if it made sense and for me it actually makes more sense to use it in that scene of ROTJ than either of the times it was used in the PT.

But in ESB it's never necessary.

You could argue that Artoo might have avoided falling to floor when Luke was destracted while lifting him with the Force but he was surprised and they seem to need to warm up before being used.

And the marsh gas problem is a much better get around for avoiding falling in the bog than Capt Antilles not keeping up on his warranty payments is in EU.
