If EHang's vision for personal pilotless aircraft wasn't quite wild enough for you, then get a load of the drone-maker's latest idea. After wowing CES attendees with a prototype of a single-passenger drone this year, the Chinese company has now teamed up with a biotechnology firm to adapt the vehicle for emergency organ deliveries.

The idea of using drones to deliver urgent medical supplies has rightly garnered quite a bit of interest. Last year Australian startup Flirtey took off on the first FAA-approved drone delivery, bringing medication to a clinic in rural Virginia. Another startup, Matternet, has also been chipping away at this problem for years, while similar projects are underway in Syria and Rwanda.

But ferrying packages of drugs with small quadcopters is one thing, carrying artificial organs in what is essentially an un-piloted helicopter is another. As the EHang's 184 drone is designed to autonomously carry an entire human from one location to another within 10 mi (16 km), you might think that carrying just one part of a human would make for light work.
