On SVN 11408 (42 Beta), Partisan transporting a jet bomber in his pocket.
I had just moved the bomber to the base he was at when I moved him out he was transporting the bomber with him. This is not a bug with rebase mechanism for the air unit because in the earlier post I made about the ICBM-packing Partisan, the way I loaded an ICBM on to him was the same way you would with a sub. I built the missile in the city and noticed the 'Load Unit' option on the missile. Knowing I had know subs capable of transporting missiles in that city I clicked it out of curiosity and low and behold it loaded ...into Partisan's backpack. So the bug would appear to be with the Partisan units transport capabilities. Assuming they were only meant to transport captive land units and not Minuteman IIIs / B-52 Bombers.
That's the face of some serious concealed carry.
