It involved a C-17 aircraft and a Chaparral eVTOL (electric vertical takeoff and landing) developed by Elroy Air. The C-17 is a Boeing-made military transport aircraft of enormous proportions.

Able to carry up to 500 lb (226 kg) over a distance of up to 300 miles (482 km), the Chaparral C1 sounds like a promising autonomous VTOL (vertical take-off and landing) aerial cargo platform.
