It sounds like an engineering fantasy, or maybe an episode from Mission Impossible: A flock of small, single-use, unpowered delivery vehicles dropped from an aircraft, each of which literally vanishes after landing and delivering food or medical supplies to an isolated village during an epidemic or disaster. And it would be nothing more than a fantasy, were it not that the principle behind disappearing materials has already been proven.
