Drones Designed to Disappear

Disappearing Act
 ICARUS Mid-stage Disappearance
MIT founded Morse Corporation of Cambridge, MA has developed a drone designed to self-destruct and disappear after its mission is accomplished.  It's called ICARUS or Inbound, Controlled, Air-Releasable, Unrecovered System project.  

DARPA Funded
DARPA, the Pentagon's Advanced Research Projects Agency, provided Morse $8million to create an aerial disappearing delivery system.  Essentially drones deployed from aircraft, deliver their payload and then self-destruct and disappear.

ICARUS
ICARUS can fly 100 miles, land within 30 feet of its target and dissolve within 4 hours or within 30 minutes of sunrise.  It's in a highly advanced research stage right now.  It's for the military in dangerous situations.  For instance, to deliver blood supplies without compromising their position.

Components
ICARUS is made of film with a guidance system smaller than a tennis ball. The polymers that comprise the rest of it are extremely sensitive to sunlight and heat, causing them to dissolve into liquid after a short amount of exposure.  Only the payload and guidance system remain.
