LA SELVA BEACH — Nestled amidst cypress trees and a blanket of thick coastal fog lies an inconspicuous workshop where Parallel Flight drones are being tinkered with and tested. The “Firefly” — weighing 120 pounds — looks only faintly like its hobbyist cousins and more resembles a small aircraft.

It stands roughly 3 feet tall and has a more than 5-foot wingspan. And here, form is function. The startup’s drones are specialized to transport heavy loads: firefighting supplies, industrial packages and even human organs for transplants.
