Stopstart is right, operators love the J and get fed up of people who have no knowledge of the ac slagging it off. I have worked with USAF J mates who also are more than pleased with it.
As for the Mk 5, there is nothing wrong with it that was not wrong with the Mk 1 before the probe was fitted. The trim issues only occur with no load and full fuel. Stick the crew bags and GEs toolset up the front and the problem goes away. We should have the option of fitting the probe soon anyway.
I hope the luddite winging will stop soon as the ac is performing extremely well now with good servicability rates (better than other similar types).
