The blue one is indeed the latest one - I guess the guys just haven't updated their web sites yet!
If you get it, let me know what you think - always looking for ways to improve it!
BTW, the "old" orange one does not have helicopters in now - it was just getting too large so I split the books up and there is a separate helicopter book now. The blue one (with the 757) is about 40 pages larger. The ones available cheap on ebay is just the remainder from a rather large print run! That was the version that the guy from BALPA Log reviewed and liked - the blue one is just better.
