Here is mine. 727 captain by Captain Sim.

E-mailed them and they said the box will be released, but they don't know when.

As far as I know there is no boxed version yet, so the only place you can find it is at their site.
BTW today they have great sale there, you can get the 757, C-130 and other for $9,99 only. Just got all expansions for my C-130
