Back last century I remember a previous conversation about the airdrop of water bottles for humaniatrian relief. The concensus was it was better for them to be dropped frozen solid as more would survive, even with a damaged bottle it would take some time for it to melt away. However, keeping it frozen in the aircraft was seen to be the problem.
As to free drop from height, remember the US drops to Kosovo. Some of these were high altitude drops where the container of MRE was ripped open (by a static line) on exit and the MRE sachets allowed to free fall.
When you're starving even an MRE is welcome and can't kill you if it hits you on the head from 12000 ft. But maybe dropping Pork and Beans to Muslims is a tad thoughtless.
