Johns Hopkins University researchers managed to deliver refrigerated blood on a three-hour drone flight across the Arizona desert. According to dronelife.com, itโ€™s believed to be the longest medical delivery by drone ever completed.

Crucially, the blood made it to its destination in a usable state, thanks to an onboard temperature-control system.

The record-breaking flight was more than a lark. It confirms the potential for using unmanned drones to deliver medical specimens from places where land and conventional air transport would be difficult or impossible.

โ€œWe expect that in many cases, drone transport will be the quickest, safest and most efficient option to deliver some biological samples to a laboratory from rural or urban settings,โ€ Hopkins prof Timothy Amukele told dronelife.com.
