For centuries, though, they used oars to move passengers and cargoes about the capital.
The drones have a cargo compartment about the size of a mailbox that can transport packages up to 6.5 pounds a distance of six miles, according to Flytrex.
What proved stunning to scientists who rushed down to examine it was the cargo: About 2 tons of living sea creatures, some of which could devastate local sea life populations.
The helicopters, officials said, landed and seized the boat along with its cargo, about 2,000 pounds of cocaine.
Biological molecular machines are used to transport cargo about a cell (e.g., kinesin), to power the movement of organisms (e.g., bacterial flagellar motors), to synthesize proteins (e.g., the ribosome), and to separate strands of DNA (e.g., helicases).
It had arrived in the early morning hours and had begun offloading its cargo about 2 a.m., officials said.
The pictures here are from a series called "Human Cargo", about women who are transported from one country to another to be sold.
They each have about equal cargo capacity (the Subaru trails here, but not by much), have four-wheel drive and smart, well-designed interiors.
The rent, based on the volume of cargo, starts at about the same amount that it did in 1994, and escalates as the volume increases.
Although the cargo volume is about the same as last year's model, the space is about five inches longer and the opening is about an inch closer to the pavement.
