Yes l knew that, but it is still classed as tech.
Which was my point, any aircraft of any age can and will go tech.
As for the CFU yesterday, A300 was used to operate an earlier A321 flight, due to the tech a/c in AGP.
One of the A300 was indeed being worked on at LGW, one of which was planned to be available to engineering on Monday, so the CFU was operated when the A300 returned from the earlier flight.
