Sorry, but UFO transfer doesn't work properly in 2.2. I don't think you can transfer a UFO. (or at least not without some problems)
I'm not sure aircraft transfer works properly, either. I had two Firebirds at HQ until my second base got its buildings complete. Transferred a Firebird to base #2. After the requisite amount of time, i get the message about transportation complete. Base #2 has: a new Saracen. Meanwhile, HQ still has two Firebirds, though one of them shows the status "transferring". I eventually had to sell it and buy a new one for base #2. This was on the 2.2/Jan 15 Mac binary.
