I'm interested to know where these rumours are coming from, because no one in engineering knows anything about these 744f's, because just from experience with the 767 freighters we knew about them for a while before they arrived and there was a lot of training and technical support required for the 767 freighter before it arrived and I can't see it being any different for the 744f. If the rumour is true, I would be very surprised if they arrived before the end of this year.
