I believe somebody said that he has some 744 sim time
JT did the full type course. Full QF Ground course of 2-3 weeks and then the nine full flight sims requires for the endorsement. I don't know if they gave him circuits in the aeroplane at Avalon to finish it.
I've got to say that I'm quite amazed at the response this is getting now in PPRUNE world. This is not a new thing. I remember discussing this during my type conversion onto the 744 back in 2006 and JT had done his training a few years prior to that! I'm not sure if it's the tall poppy thing or just ignorance but some of the comments here on PPRUNE just defy logic.
