The defense contractor is teaming up with nonprofit Project Lifesaver to create a version of its quadcopter Indago UAV that will help locate people with cognitive disabilities or diseases that make them prone to wandering.

Project Lifesaver was established in 1999 to equip people with with autism, Alzheimer's, Down's syndrome, and other mental issues, with a personal transmitter worn on the ankle or wrist. If the person goes missing, emergency services can track the signal, using equipment and training provided by the nonprofit. This setup has helped find nearly 3,000 people, with an average time of 30 minutes per recovery.

The nonprofit's main shortcoming is that you have to be within a mile and a half of the signal to pick it up. That's where the Indago comes in: Packing a specialized antenna produced by Canadian firm Loen Engineering, it acts as an airborne relay and expands that range to seven miles.
