calls these 73X's .. 18/132 seating (needed for the forth lav) Here's the deal... 18 craft (Ships 260-277) were delivered as X's with the original intention of the same for all new deliveries and conversion for the older machines. With the
losses caused by various reasons, the extra five seats with the 14/141 (and three lavs) regained priority and Ships 278-292 arrived as non-X. However, some nine conversion ship sets had already been purchased before the mind change and it has been decided to go ahead and use them as they, apparently, are no return/no refund
. Unless things change, only a total of 27 aircraft will end up as 73X's.
Working very hard to Fly Right....
