Ah, G-12. :-) Hadn't heard his name in a while.
(Looking about in some of the literature I have in a pile, it appears that you could operate a UH-60M at up to 23,500 with an external load, but the 155, if it has grown another 30 pounds, would exceed the 9K cargo hook. From Sans' link, it has grown almost 800 pounds, so the M may not get the chance to carry it about.
Did G-12 pick it up and put it down, or did he fly it away and fly it back and put it down? A load that heavy, in comparison the total helicopter mass, calls for very smooth flying to keep it stable during accel and decel.
