My comment about the TP400 was, of course, tongue-in-cheek. I did wonder, for a while, whether the Belfast might be used as a flight trials platform for the TP400, but apparently Airbus have contracted Marshalls to do the flight trials using a C-130;

So it's obviously just a coincidence that the TP400 project is slipping to the right and the Belfast is still minus one prop and hasn't been attended to lately.
